What is the difference between direct drive motor, linear motor, servo motor and step motor?

Answer:

Servo motor (servo motor) is the engine that controls the operation of mechanical components in servo systems. The servo motor can control the speed, the position accuracy is very accurate, can convert voltage signal to torque and speed to drive control object, closed loop control. Step induction motor: the step motor is to convert the electrical pulse signal into the angular displacement or the line displacement of the open loop control the step into the motor, the pulse open loop control.
Linear motor is also called the linear motor, linear motor is a kind of mechanical energy convert electrical energy directly into linear motion, without any intermediate conversion mechanism of transmission. It can be seen as a rotating motor cut open by radial and formed into a flat surface Direct drive motor: the short term for direct drive motor. The main point is that the motor is not required to pass the transmission device (such as a driving belt, etc.) when driving the load.
Simple, linear motor is rotating motor along the radial incision, straighten the evolution and become, by the side of the stator has evolved is called the primary, evolved by the rotor side become secondary. Like servo is closed loop control, and step motor is also called pulse motor, which is open loop control
