FAQ

What is a motor controller?

A motor controller is an electronic device that regulates the performance of an electric motor by controlling parameters such as speed, torque, position, and direction. It acts as the interface between the motor and the power supply or control system.

What types of motors do motor controllers support?

Motor controllers are designed for various motor types, including:

DC Motors (Brushed and Brushless DC or BLDC)

AC Motors (Induction and Synchronous)

PMSM (Permanent Magnet Synchronous Motors)

Stepper Motors

Servo Motors

What are the different types of motor controllers?

Open-loop controllers – Basic control without feedback

Closed-loop controllers – Use sensors for feedback (speed, torque, position)

VFD (Variable Frequency Drive) – Controls AC motors by varying frequency and voltage

ESC (Electronic Speed Controller) – Used in drones, e-bikes, and RC applications

Servo drives – High-precision controllers for servo motors

What does a motor controller do?

A motor controller:

Starts and stops the motor

Regulates speed and torque

Reverses rotation direction

Provides overload and fault protection

Enables smooth acceleration and deceleration

Interfaces with higher-level systems (e.g., PLC, microcontrollers, CAN, or Modbus)

What is the difference between a motor driver and a motor controller?

A motor driver is typically a simpler, low-level electronic circuit used to switch current to a motor (common in robotics and embedded systems).

A motor controller includes logic, feedback control, protection, and often communication features—used in industrial and commercial applications.

How do you control the speed of a motor?

Speed is controlled by:

PWM (Pulse Width Modulation) – For DC and BLDC motors

Frequency adjustment – For AC motors using a VFD

Voltage variation – Less common due to inefficiencies

Field-Oriented Control (FOC) – For PMSMs and BLDCs for high precision

What is Field-Oriented Control (FOC)?

FOC is a method used in advanced motor controllers to regulate AC motors (especially PMSM and BLDC). It transforms the motor’s variables into a rotating frame of reference, enabling precise control of torque and speed, improving efficiency, smoothness, and dynamic response.

What communication protocols do motor controllers support?

ROYPOW UltraDrive Motor Controllers support customizable communication protocols based on specific demands, such as CAN 2.0 B 500kbps.

What protection features are included in motor controllers?

Offer Voltage/Current monitor & protection, Thermal monitor & derating, Load dump protection, etc.

How do I select the right motor controller?

Consider:

Motor type and voltage/current ratings

Control method required (open-loop, closed-loop, FOC, etc.)

Environmental conditions (temperature, IP rating)

Interface and communication needs

Load characteristics (inertia, duty cycle, peak loads)

What are common applications of motor controllers?

Suitable for Forklift Trucks, Aerial Working, Golf Carts, Sightseeing Cars, Agricultural Machinery, Sanitation Trucks, ATV, E-Motorcycles, E-Karting, etc.
