Sensor motor

Types of sensor motor

A sensor motor combines a motor (like DC, servo, or stepper motors) with sensors to provide feedback on its position, speed, or motion. In the context of robotics and electronics, these sensors are crucial for applications that require precise control and information. Here are several types of sensor motors:

• Brushless DC Motors (BLDC)

  These motors are popularly known as sensor motors. They come with an electronic speed controller that provides information on the motor's position, enabling precise commutation and control. The common types of sensors include; Hall Effect sensors, which are widely used because of their cost-effectiveness, and magnet sensors that provide high precision. The sensorless controllers use back electromotive force (BEMF) to determine the motor's position.

• Servo Motors

  These motors are usually applied in robotics, automation, and CNC machines. They come with a feedback potentiometer, giving them a high degree of positional accuracy. There are different types of servos, including; rotary, linear, and industrial servos. The rotary servo motors use PWM signals for control, while linear servos convert rotational motion to linear motion. Industrial servo motors are high-powered and are tailored for specific applications.

• Stepper Motors

  Stepper motors come with their own drivers that provide feedback of the motor's position. They move in discrete steps, making them ideal for applications requiring precise positioning without feedback. The closed-loop stepper motors incorporate sensors and feedback mechanisms for accuracy, while open-loop steppers operate without feedback but are less precise. Hybrid stepper motors combine the features of permanent magnet DC motors and traditional steppers.

• AC Induction Motors

  These motors can be fitted with encoders to provide feedback on the position and speed. The encoder feedback allows for vector control, enabling precise torque and speed control. The rotary induction motors are popular for industrial applications, while the squirrel cage induction motors are widely used due to their robustness. The slip ring induction motors offer high starting torque and speed control.

• Brush DC Motors

  These motors can also be fitted with gear sensors to provide feedback for speed and positional control. The feedback loop allows for consistent control over varying loads and speeds. They are popular for applications requiring simple speed and positional control.
