Why use trapezoidal or other acceleration methods for stepper motor control? The starting speed of stepper motor is generally about 150 to 250RPM according to the different motors. If you want to operate at a high speed, you must start at the following speed first, gradually accelerate until the maximum speed runs for a certain distance and then slow down gradually. Only when the starting speed is below can you stop. The common acceleration methods include graded acceleration, trapezoidal acceleration, s-word acceleration, etc.


Stepper motor is widely used in various fields. Stepper motor is widely used in various fields of production practice. Its biggest application is in the manufacture of CNC machine tools, because the stepper motor does not need a/d conversion, can directly convert the digital pulse signal into angular displacement, so it is considered as an ideal implementation component of CNC machine tools. Early stepper motor output torque is relatively small, can not meet the needs, in the use of the hydraulic torque amplifier together with the composition of the hydraulic pulse motor.
