FAQ
What is motor control?
Motor control is a set of tools that regulate an electric motor's operation in a specific way. They perform a variety of essential tasks, such as starting and stopping a motor, changing the direction of rotation, choosing and controlling the speed of rotation, regulating the torque, and overload and fault protection.
What is a motor controller? How does it work?
These devices are used for controlling how an electric motor operates. They choose whether to rotate in the forward or reverse direction, accelerate, or decelerate, as well as other operating parameters.
Our engineers, who are experts in motor control design, create solutions to ensure efficient and reliable operation of motors in various applications.
What types of motor controllers exist?
- Variable-frequency drive (VFD)/Variable-frequency inverter
- Servo drive
- Soft starter
- Multi-axis motion
- Stepper motor
- Brushless and brushed DC motor controllers
What is the difference between BLDC and PMSM motors?
BLDC means brushless DC electric motor, and PMSM is a permanent magnet synchronous motor. They are similar, but each has its own characteristics.
Promwad offers firmware development services for BLDC motors to help you achieve high performance and reliability. Our experience in FOC firmware services, industrial network design, and low-level programming allows us to develop firmware that accurately controls motor speed, torque, and direction.
Our engineering team can also provide you with firmware development services for PMSM. We create reliable PMSM motors for a variety of industries, including electric vehicles, robotics, industrial machinery, and automation systems.
Furthermore, if you need to develop an ACIM motor, contact us to learn more about our firmware development services for ACIM. We build solutions that guarantee efficient, reliable, and precise control of your motors.
