By receiving pulse current, the control of speed, position, the direction in the stepper motor can achieve. The number of the pulse determines the position of the stepper motor. The rate of the pulse determines the speed of the motor. The direction of the pulse determines the rotation speed of the m

　　The Stepper Motor is an open-loop motor that converts angular displacement into angular displacement. When the stepper motor does not lose a step, the speed, the position of the stop is determined by the frequency of the pulse signal and the number of pulses. When the stepper motor receives a puls

　　The two-phase stepper motor usually has three types: four, six, and eight wire. The schematic diagram is as follows:　　In reality, the two-phase stepper motor comes from four phases. The four-wire type is drawn in series or parallel and then draws four wires. In terms of six wire types, one is draw

1. The Heating Reason for The Stepper Motor As for various stepper motors, it’s internal structure consists of an iron core and winding coils. There is resistance in the windings, the current will cause a loss, which is proportional to the resistance the square of the current. If the current is not

　　The stepper motor is a widely used actuator, which is used in the various automatic control system. Recently, I participate in the project of grating splicing device for laser compression, whose accuracy requirements reaches up to nanoscale, which has a high requirement for the stability of the sy

　　At Present, the driving motor of the smart lock has a large size and low torque. Besides, the steering is single, the control is unstable, which is easy to fail and low life.　　To solve the above-mentioned deficiency, I.CH design a new smart lock gear motor, which is a simple structure, stable cont
