With today’s constantly changing industrial landscape, there has never been a greater need for precision, efficiency, and intelligent automation. At the center of this evolution is a technology that is changing how we make machines move and think. This includes the 36V Brushless DC (BLDC) motor controller.
BLDC Motor controllers are the perfect combination of data processing and motion control, providing smarter performance and transforming manufacturing, robotics, and automation systems all over the world.
The intellect behind motion
A 36-volt brushless DC (BLDC) controller essentially works on a microcontroller unit (MCU) that functions as the brain of the system. The intelligent hub collects data from sensors, deciphers the data, processes the data, and uses complex algorithms to control the motor with pinpoint detail and accuracy.
Whereas previously, the brushed motor would operate based on a physical switch for supplying energy to the load, in a BLDC controller, the commutation is now electronic, and there are constant data streams to inform the decision-making process. There is a feedback loop formed by the data series to continually improve itself.
Advanced data and motion control is not only a promise of technology; it marks a profound turning point in the operation of industrial systems. The combination of computational intelligence and precise motor control comprises a motor and controller that enables machines to respond to input and output to varying conditions, to predict the need for maintenance, and to communicate as part of broader connected automation systems. Brushless.com integrates these same intelligent architectures into its modular controller series, designed for industrial automation and robotics applications that demand both speed and adaptability.
Real-time data for smart control
Whether built as integrated BLDC controller ICs or modular 36V control boards, today’s BLDC motor control systems are designed to gather and process multiple data streams simultaneously. As the rotor turns, Hall-effect sensors, or sensorless back-EMF methods, can only continually provide the position of the rotor’s angular position, so the controller has the right information to move to electronic commutation.
The recognition of the position of the rotor allows current to flow through the stator windings at optimal points in time, allowing for the utmost efficiency of energy consumption.
Current sensors and voltage sensors introduce yet another level of intelligence by retaining information about load conditions and power usage in real-time. This allows the controller to provide protection against potentially damaging overcurrent situations while finely regulating charge output.
If a machine encounters unexpected resistance or variability in load, the controller can react quickly and adjust output to keep performing as expected.
By monitoring temperature, the sensors provide thermal awareness in the motor and controller components, avoiding overheating issues that could lead to catastrophic and premature failures. The temperature monitoring allows adjustments to the operation or shutdown to happen automatically if the thermal conditions dictate the need for protection.
This creates a level of self-aware inside the controller that can take measures to protect itself and prolong its operational lifespan.
In addition to internal sensors, the controllers can also accept commands from external sources such as potentiometers for manual control, or even host electronic control units (ECUs) and other higher-level automation systems, such as programmable logic controllers (PLCs).
This allows for a wide view of multi-source inputs, which makes these controllers ideal for complex industrial settings where machines work with multiple sources of automated control, in conjunction with human input.
Sensorless or sensored?
With various sensing options available, selecting the right feedback approach becomes a key design consideration. Sensorless BLDC motor control reduces wiring and cost and excels at medium-to-high RPM. Sensored (Hall or encoder) control wins when you need rock-solid low-speed torque, holding, or precise indexing.
Mixed fleets are common: a 36V sensorless BLDC motor controller for conveyors plus a 48V sensored unit for pick-and-place axes. A two-minute selector at Brushless.com maps required low-speed torque and start/stop profiles to the right control mode.
For engineers comparing performance options, Brushless.com’s 18–72V BLDC controller families cover both sensored and sensorless designs — making it easy to choose between low-speed precision and high-speed efficiency.
Typical setups:
- 36V sensorless controllers for conveyors and packaging lines
- 48V sensored controllers for precision robotics
- 72V CAN-enabled controllers for AGV traction and steering systems
Smart processing to use data responsively
Simply having raw data isn’t enough to achieve smart performance—it’s the advanced algorithms that run on the MCU that make the data into meaningful motor movement from sensor data.
The next generation of BLDC controllers, often implemented through dedicated BLDC controller ICs or MCU-based driver boards, utilize advanced control algorithms such as Field-Oriented Control (FOC) and Proportional-Integral-Derivative (PID) loops. These methods allow precise torque and speed regulation even in sensorless BLDC motor control systems, enabling compact, cost-effective, and high-efficiency designs. to provide the most optimal Pulse Width Modulation (PWM) signals. These algorithms are always looking at the incoming feedback data to change motor action to achieve the speed and torque properties needed for that application.
The level of intelligence has moved beyond basic control to include full and complete safety and protection systems. The controller is continuously analyzing data for fault conditions, overvoltage conditions, overcurrent conditions, or heat conditions.
When it sees a threat, it will immediately take action to protect the system. This preventative thinking can reduce the downtime of the system and prevent total failure that would stop the production line.
Some high-end industrial controllers are beginning to apply machine-learning models for pattern-based fault prediction, though most practical systems still rely on threshold-based data analysis today. This means that the systems analyze patterns of historical data and can predict when a component is going to go bad and when the best time to maintain it is. They will also optimize energy use by looking at actual use rather than theoretical load evaluation.
Brushless.com controllers implement these control algorithms through dedicated MCU-based driver boards with real-time protection and field-upgradeable firmware.
This allows OEMs and integrators to keep hardware constant while evolving the algorithm to meet new production needs.
Precise motion control for visible outcome
All that data processing results in precise gate signals for the power stage MOSFETs (the electronic switches that control how much current flows to the motor windings). The timing and sequencing of how those gate signals are utilized determine the rotational characteristics of the motor.
Everything from linear acceleration curves to positional accuracy (hold position, or be able to control the position). And since there are no mechanical brushes, there are no friction or sparking wear points, and electronic commutation allows for maximum efficiency in the full speed range.
This precision of control is impacting applications across industries. In robotics and industrial automation, 36V three-phase BLDC motor controllers deliver repeatable, smooth motion control essential for precision assembly.
For mobile or battery-powered applications, sensorless BLDC motor controllers provide reduced wiring complexity and higher energy efficiency — ideal for AGVs, drones, or compact production systems.
CNC machines achieve tighter tolerances while maintaining faster cycle times. Conveyor systems adapt their motor speed based on the material flow, consuming less energy while processing material at less than full speed.
Application Snapshots
These use cases illustrate how different control configurations map to real-world voltage levels and performance needs.
- CNC: FOC + encoder feedback improves contour accuracy and reduces cycle jerk.
- Conveyors (36–48V): Sensorless BLDC control trims energy when line is starved, preventing jams.
- AGV/AMR (48–72V): CAN-enabled 3-phase BLDC motor controllers synchronize traction and steering.
Each application above corresponds to controller options available across the 18–72V range. Because these controllers automatically adapt to system voltage (24V/36V/48V typical), engineers can standardize on a single hardware platform across multiple machine types.
The industry advantage of smarter operation
The data and operation control in the 36V BLDC motor controller result in an actual value, functionally benefiting an industrial operation. Precision and efficiency literally mean higher quality, with reduced energy costs. Reduced energy costs mean reduced overall cost of production.
The combination of eliminating mechanical brush systems with intelligent protection means reduced maintenance, and helps to extend the lifecycle of the system to optimize the total cost of ownership.
It is noteworthy that modern controllers now come equipped with standard communication interfaces (CAN bus, UART, Ethernet, etc.) that support integration into Industrial IoT and smart factory systems. Controllers with CAN bus suit multi-axis robots and AGVs; UART is perfect for embedded boards; Ethernet/Modbus-TCP helps PLC lines scale. A consistent message map (faults, RPM, temperature, current) shortens commissioning time and feeds predictive models. Industrial deployments live or die by integration. This integration provides remote monitoring, real-time diagnostics, and the ability to tie into enterprise resource planning systems, making a truly intelligent production environment.
The other aspect of the MCU’s programmability is that adaptability is something that cannot be found with mechanical systems.
With controllers, they can be modified for a different application, adapted for an altered load condition, and updated with advanced algorithms, without any hardware modification. This ability to operate in flexible modes in the future protects investment and allows manufacturers to maximize their systems as their needs change.
