1. Brief Description

Stepper transmission motor manufacturers is an open-loop control motor which converts electrical pulse signal into angular displacement or linear 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".

Stepper transmission motor manufacturers’ rotation is based on the Angle of the fixed step by step. The angular displacement can be controlled 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, so as to achieve the purpose of speed regulation.

2. Operating Principle

Stepper transmission motor manufacturers is a kind of induction motor, its working principle is to use electronic circuit, the direct current into a time sharing power supply, polyphase timing control current, with this current for the stepper motor power supply, stepper motor can work normally, the driver is for the stepper motor time sharing power supply, polyphase timing controller.

3. Application

Although Stepper transmission motor manufacturers has been widely used, but stepper motor is not like ordinary dc motor, ac motor in conventional use. It must consist of double ring pulse signal and power drive circuit. Therefore, it is not easy to use stepper motor, it involves machinery, motor, electronics and computer and many other professional knowledge. As an executive component, stepper motor is one of the key products of electromechanical integration and is widely used in various automatic control systems. With the development of microelectronics and computer technology, the demand of stepper motor is increasing day by day.

4. Menus

Stepper transmission motor manufacturers can be divided into many types in their structural forms, including Variable w (VR), Permanent Magnet (PM), Hybrid Stepping motor (Hybrid Stepping motor,HS), single-phase Stepping motor, plane Stepping motor and so on. Among the stepper motors used in China, reaction Stepping motor is the most common one.The performance of stepper motor is closely related to its control mode. From the perspective of its control mode, the stepper motor control system can be divided into the following three categories: open-loop control system, closed-loop control system and semi-closed-loop control system.Semi-closed-loop control systems are generally classified as open-loop or closed-loop systems in practical applications.

5. System of Selection

Stepper transmission motor manufacturers and driver selection method:
Determine how much torque is required: the static torque is the choice step
Stepper motor (FIG. 3) Stepper motor (FIG. 3)
One of the main parameters of the feed motor. When the load is large, the high-torque motor should be used. When the torque index is large, the motor shape is also large.
Judge the motor running speed: when the speed is required to be high, the motor with large phase current and small inductance should be selected to increase the power input. And when selecting the driver, use a high supply voltage.

6. Operating Principle

Usually the rotor of the Stepper transmission motor manufacturers is a permanent magnet. When the current flows through the stator winding, the stator winding generates a vector magnetic field. The magnetic field will drive the rotor to rotate by an Angle, so that the rotor's pair of magnetic field direction is consistent with the stator's magnetic field direction. When the stator's vector magnetic field rotates by an Angle.

The rotor also rotates at an Angle with the magnetic field. With each input pulse, the Stepper transmission motor manufacturers moves one step further before turning an Angle. Its output angular displacement is proportional to the number of input pulses, and the speed is proportional to the pulse frequency. Change the order in which the windings are energized and the motor will reverse. Therefore, the number of pulses, frequency and the electrification sequence of each phase winding of the motor can be controlled to control the rotation of the stepping motor.
