Used stepping motor should be able to find, the device cannot directly to run when starting frequency, need to have a low speed up the running speed of the boot process, gradually stop running frequency can't immediately drop to zero, there must be a process of high speed gradually slow down to zero. Manufacturers in the design of motor, which requires you need according to the following situation to do process control acceleration and deceleration of the motor, stepping motor speed depends on the pulse frequency, the rotor teeth number and beats. The angular velocity is proportional to the pulse frequency, and with pulse on time step. Thus the rotor teeth and run for several cases, as long as the control pulse frequency can obtain the required speed. Because of the stepper motor is initiated by means of its step torque, in order not to happen out of step, start frequency is not high. Diameter increases, especially with the increase of power, rotor inertia increases, start the operating frequency and the highest frequency may differ ten times as much. According to the above situation, manufacturers need to optimize the relevant aspects of design, and use a certain technology ensures that the step motor running through three stages, acceleration, uniform speed and slowdown as far as possible and ensure the process of acceleration and deceleration time short, constant speed long time as far as possible. the main products: stepper motor, brushless motor, servo motor, stepping motor drive, brake motor, linear motor and other kinds of models of the stepper motor, welcome to inquire.
