Do you need a speed reducer to step into the motor? What is the effect of a speed reducer?
As with your car, though the throttle is able to control the speed of the car, it must be switched lower.
Stepper motor and deceleration machine only purpose is to increase torque talked low speed step itself is low speed motor precision without reducer precision is higher That can only be added reducer in order to increase the output torque of the motor.
Reducer between prime mover and work machine or actuator has a function in matching speed and transfer torque reducer is a relatively sophisticated machinery, the use of its purpose is to reduce rotation speed, increase torque. According to the transmission series, it can be divided into single stage and multi-stage reducer. According to the tooth mill wheel, it can be divided into cylinder gear reducer, conical gear reducer, and cone-cylindrical gear reducer. According to the layout of the transmission, it can be divided into expansion, shunt and coaxial reducer. Reducer is a kind of the closed in rigid casing of gear transmission, worm drive and gear - worm drive composed of independent components, commonly used for the original reduction drive device between moving parts and working machine. The function of matching speed and transfer torque between the original motivation and the working machine or actuator is very extensive in modern machinery.
Look for the torque that you need, if you go beyond the range, the only object is to increase the torque. Step by step motor is an open loop controlling element which converts electrical pulse signal into angular displacement or line displacement. In the case of the overload, motor speed, stop position depends only on the pulse signal frequency and pulse number, and not affected by load change, when the stepper driver receives a pulse signal, it is driving a stepper motor according to set the direction of a fixed Angle, known as the "step Angle", its rotation is based on the Angle of the fixed step by step. It can control the amount of angular displacement by controlling the number of pulses, so as to achieve accurate positioning. At the same time, the speed and acceleration of the motor can be controlled by controlling the pulse frequency to achieve the goal of speed adjustment.
