Motor Controllers
Description:
Motor controllers are devices that exhibit accurate control over motor operations. They are essential for any motor control application. Signals are provided from motor controllers to motor drives, which in turn drive the motors interfaced with them. A typical motor controller system includes amplifiers, power supplies, position control circuitry, and user interfaces. Several types of motors use motor controllers as part of their operations. Stepper motors, hydraulic and pneumatic control systems make use of motor controllers extensively. Motor controllers vary from each other in terms of operating parameters, electrical ratings, features, and configurations.
Types:
Motor controllers are generally categorized into the following types:
- Stepper motor controllers
- DC motor controllers
- AC motor controllers
- Servo motor controllers
- Brushless motor controllers
- Brushed motor controllers
Specifications:
Some of the important specifications of motor controllers are listed below:
- Maximum output voltage
- Rated power
- Continuous output current
- Peak output current
- AC supply voltage
- DC supply voltage
Advantages:
The major advantages of motor controllers are listed below:
- Motor Controllers are endowed with many protective features like thermal overloads, magnetic overloads and fuses
- AC motor controllers have increased reliability, flexibility, greater speed ranges, and low motor maintenance costs
- High resolution, torque, and velocity are offered by a stepper motor controller
- The LVP type of AC motor controller de-energizes the motor on low voltages and inhibits it from restarting automatically
- The LVR type of AC motor controllers de-energizes the motor on low voltages and helps it to restart when the voltage gets restored to normal
- The LVRE type of AC motor controllers helps in the maintaining the motor across the line
Applications:
Motor controllers are commonly used in domestic, medical, commercial, industrial, robotic, and automotive applications. Personal care products, home appliances, heating and cooling equipments, ventilation fans, office equipments, ventilation and air conditioning equipment, engine driven vehicles, electric vehicles, aircraft carriers, power tools, etc are some of the common applications of motor controllers.
