The stepping motor is an open loop control element which transforms the electric pulse signal into angular displacement or linear displacement. In the case of non overloaded, the motor speed and stop position depends only on the pulse frequency and pulse number, regardless of load changes, when the stepper driver receives a pulse signal, it drives stepper motor to set the direction of rotation of a fixed angle, called "step", it is the rotation of the fixed point of the operation step by step. Number of pulses can be controlled by controlling the angular displacement, so as to achieve the purpose of accurate positioning; at the same time by controlling the pulse frequency to control the motor rotation speed and acceleration, so as to achieve the purpose of speed.
There are 2 kinds of motors, not servo motors or stepping motors. The servo is better, but the price is higher. Choosing the right stepping motor according to the accuracy can save the cost.
Stepper motor is a kind of motor which can realize precise position control in open-loop control conditions. It has the characteristics of high performance price ratio, and is mainly used in low and big torque occasions. But need to drive controller, professional to run, analog control mode, such as leadshine products such as M542, are all digital control, such as Yingna Shi EZM552.
