The difference between pulse motor and servo motor
The step motor is synchronous motor, which is running in step by step and is open loop. The servo motor is running continuously, with the encoder feedback, it is closed loop.
The pulse motor you're talking about should be a step motor, right? If it is a step motor, it is also a kind of servo motor. He is the corresponding step Angle for each pulse. The motor speed is proportional to the frequency of the pulse, and the rotation Angle is proportional to the number of pulses. One way to tell the difference is: you're asking the difference between apples and fruit, because apples are fruit. But it's just one of many fruits Well, I'm not saying that stepping into the motor is a kind of servo motor Servo motor includes: step motor, dc servo motor, ac servo motor, linear motor, etc. So let me give you the example above.
But if you ask the difference between the stepping motor and the ac servo or dc servo, I can tell you: Stepper motor start-up needs a slow speed, and can control through pulse, and is inversely proportional to the speed and torque of the motor, the higher the speed, torque is smaller, and the highest speed is not more than 1500 r and his itself has no feedback device, speed up the easy step, and the low speed easy to shake. And other kinds of motor position control (pulse) and speed (analog control) with a feedback device, constant torque under the rated speed, the speed of tens of thousands of turn, and because there are feedback device step will not be lost
