What is a deceleration stepper motor? The deceleration stepper motor is a widely used deceleration device. The following will introduce the introduction of stepper motors, reducers, and deceleration stepper motors, as well as their structural components.

Stepper motor

The stepper motor is a kind of induction motor. Its working principle is to use the electronic circuit to convert the direct current into a time-sharing power supply. The multi-phase sequence controls the current. Using this current to power the stepper motor, the stepper motor can work normally. The driver is a time-sharing power supply for the stepper motor, a multi-phase timing controller. Stepping motor is an open-loop control motor that converts electric pulse signal into angular displacement or linear displacement. It is the main executive element in modern digital program control system and is widely used. In the case of non-overload, the speed and stop position of the motor only depend on the frequency and number of pulses of the pulse signal, and are not affected by the load change. When the stepper driver receives a pulse signal, it will drive the stepper motor to press The set direction rotates a fixed angle, which is called "step angle", and its rotation runs step by step at a fixed angle.

Reducer

The reducer is an independent component consisting of a gear drive, a worm drive, and a gear-worm drive enclosed in a rigid housing. It is often used as a deceleration drive between the prime mover and the working machine. It plays the role of matching speed and transmitting torque between prime mover and working machine or actuator, and is widely used in modern machinery. Generally used for low-speed and high-torque driving equipment, the motor, internal combustion engine or other high-speed running power is used to achieve the purpose of deceleration through the gear with a small number of teeth on the input shaft of the reducer and the large gear on the output shaft to achieve the purpose of deceleration. Ordinary reducer There will also be several pairs of gears with the same principle to achieve the ideal deceleration effect. The ratio of the number of teeth of the large and small gears is the drive ratio. The drive source of the reducer can be used by DC motor, stepper motor, coreless motor, micro motor, this kind of deceleration equipment is also called DC deceleration motor, stepping deceleration motor, coreless deceleration motor, micro deceleration motor and other driving deceleration equipment.

Deceleration stepper motor

The deceleration stepper motor is composed of a reducer (gearbox) + motor. The motor can provide a considerable high-speed speed, but the torque is very small, and the resulting motion inertia is quite large; the function of the reducer is to control the lowering speed. , Increase the torque, reduce the inertia generated by the movement, and have reached the ideal speed and torque; for example, common electric curtains and electric rolling gates all use geared motors with slow speed and large torque.

To put it simply, the stepper motor can be controlled at a fixed length and a fixed speed. For example, the speed of the motor can be set freely when the workbench moves 1 meter. Rare application examples include, for example, the workbench of a milling machine. on the stepper motor. The difference between the two is that the stepper motor can achieve constant speed and timing (you can set how long you want to go and how fast you want to turn), but the speed of the decelerated stepper motor is determined by the reduction ratio and cannot adjust the rotation. The speed is fast or slow; but the torque of the stepping motor is small, and the rolling torque of the geared motor is large.
