Presumably many equipment manufacturers have encountered the three-phase asynchronous motor burning coil failure, mainly because of overcurrent caused, sometimes the voltage is too high or too low, but also hard coil heat, so we must first check whether the voltage during operation is similar to the rated voltage; Today, Senli Xiaobian will take you to understand the reasons for the current short circuit.

When the motor is just started, the rotation is static; The rotating magnetic field of the AC brake motor cuts the rotating magnetic field at a relative speed, so that the rotating magnetic field senses a high potential and flows a large current, which is also called the starting current; Here is a simple understanding of the requirements of Senli Motor.

Because of friction, vibration, insulation aging and other reasons, there are some failures in AC brake motors, such as the sudden change of temperature during operation, which will cause the motor to burn, vibration will cause the silicon steel sheet to loose and produce large electromagnetic noise; However, if we check and eliminate these faults in time, we can effectively prevent problems.

Direct current motor is a motor that converts direct current energy into mechanical energy. Because of its good speed regulation performance, it has been widely used in electric drive. Dc motor according to the excitation mode is divided into permanent magnet, separate excitation and self-excitation3Among them, self-excitation is divided into parallel excitation, string excitation and compound excitation3Seed.

Dc motor is a kind of motor that converts direct current energy into mechanical energy, and has good speed regulation performance, so it is widely used in electric driving. If the excitation method can be divided into permanent magnet, he excitation, self-excitation three types, of which self-excitation can be divided into parallel excitation, series excitation, compound excitation three. Then here is a simple understanding of the working principle of DC motors with Senli Motor Xiaobian requirements!

The mechanical characteristics of the motor are soft and hard, for example, under the rated voltage, if the load changes, the speed change is small, then we call the mechanical characteristics hard, on the contrary, if the speed changes greatly, it means that the mechanical characteristics are soft; Then here is a simple understanding of the mechanical characteristics of three-phase asynchronous motors with Senli Motor Xiaobian.

We know that the single-phase motor can turn positive and negative, but under normal circumstances the spindle steering is positive, can be divided into running capacitance, starting capacitance, and no capacitance of the shield motor; So today, Senli Motor Xiaobian will take you to a simple understanding of the positive and negative conversion mode of single-phase asynchronous motors.

Motor positive and negative control, the phase sequence of the power supply can be any two relative adjustment, called commutation, usually V phase unchanged, through U and W switching, in order to ensure that the two contactors can reliably exchange the phase sequence of the three-phase asynchronous motor, wiring should make the contactor's upper connection consistent, in the contactor's lower port phase adjustment.

Torque, refers to the force of the transmission; A motor, also known as a motor, is an electromagnetic device that converts or transmits electrical energy according to the law of electromagnetic induction. Torque motor torque in the circuit with the letter M (the old standard with D), its main role is to produce driving torque, as a power source for electrical appliances or various machinery.

The vertical motor and the horizontal motor have obvious differences in appearance, the vertical is fixed with the shaft end flange, and the horizontal organic seat is fixed. The same type of product, in the difference between the two installation methods, you can see whether the appearance of the torque motor is connected by flange or fixed by the frame.

Long axis torque motor products, suitable for winding and winding scenarios, can be customized for different industry scenarios, to meet the requirements of use. This product produced by Senli has the characteristics of reasonable structure, high efficiency, good characteristics and long service life.
Shengzhou Senli Motor19Old motor manufacturers, with a number of their own motor production lines, from the shell, shaft, rotor, stator are independent production, all products are the use of professional product quality supervision and testing equipment full inspection factory, can provide testing reports. From the shaft machining to the whole machine assembly are completed independently. Truly realize factory direct sales.
Senli motor products are used180°High temperature resistance all copper coil material, torque motor products can be used with different rotors (ordinary rotors/Steel rotor), rotor of different motor characteristics are different, we from the shell, shaft, rotor, stator are produced by the independent, all products are the use of professional product quality supervision and testing equipment full inspection factory, can provide testing reports.
