There are several classifications of stepper motors and the stepper screw linear actuator is a part of this classifications. Here we introduce DINGS’ Stepper Screw Linear Actuator in detail. The driving principle of stepper motor The rotor of a stepper motor is a permanent magnet and when an electric current flows through the stator windings, a vector magnetic field is generated in the stator windings. The magnetic field drives the rotor to rotate by an angle such that the magnetic field direction pair of the rotor coincides with the magnetic field direction of the ...

The average efficiency of hybrid motors is about 65%, while the efficiency of permanent magnet motors is about 25%. The main reasons for the difference in efficiency are the following two reasons ： The first reason is that the hybrid motor uses a silicon steel laminated stator assembly (see Figure 1)， Compared with the stator assembly formed by stamping and forming of mild steel of permanent magnet motor, the laminated stator of hybrid motor has smaller eddy current loss and the silicon steel material in the laminated structure can reduce hysteresis error ； Therefore, the ove...

Voice coil motor has the advantages of high response, high speed, high acceleration, simple structure and small volume. It is widely used in many precision positioning systems. At the same time, it is very suitable for short stroke closed-loop servo control system. The following is a detailed introduction. "How to choose a voice coil motor and its advantages" Ⅰ. How to select voice coil motor 1. It is necessary to clarify whether the voice coil motor is used to provide linear motion or swing motion, because if it is to provide linear motion, it should be selected from...

Linear stepping motor has the advantages of high-speed response, high precision, high transmission stiffness, fast speed and unrestricted stroke length. It’s principle is to prevent the relative rotation of screw nuts and make the screw move axially. The following describes in detail "the advantages and principle of linear stepping motor" I Advantages of linear stepping motor 1. High speed responsiveness Generally speaking, the dynamic response time of mechanical transmission parts is several orders of magnitude larger than that of electrical components. Because some ...

The screw stepping motor is mainly used to prevent the relative rotation of screw and nut, so as to make the screw move axially. It can carry out angle control according to specific commands and has self-locking capability which can realize rotor positioning during motor stops. The following is a specific introduction to the "application and principle of screw stepping motor". I. Application of screw stepping motor 1. When the screw stepping motor works, the winding of each phase is not constantly energized but energized in turn according to a certain method. 2....

Brushless DC motor has the advantages of traditional DC motor. It has small volume and light weight. It will not produce sparks. It is especially suitable for explosive places. When it needs to be disassembled, the dust and dirt on the motor surface should be cleaned. The following is a specific introduction to "characteristics and maintenance of brushless DC motor" I. Characteristics of Brushless DC motor 1. It can replace DC motor speed regulation, frequency converter + variable frequency motor speed regulation, asynchronous motor + reducer speed regulation. 2....

Compared with ordinary DC motor, Slotless BLDC micro motor adopts slotless rotor which has the advantages of smaller volume and lighter weight. The advantages and disadvantages of slotless BLDC micro motor are briefly described in below. Advantages of slotless BLDC micro motor 1.High power density : the power density of the slotless BLDC micro motor is the ratio of output power to weight or volume. The slotless rotor is lighter than the ordinary iron core rotor. The slotless rotor eliminates the eddy current and hysteresis loss generated by the iron core...
