The main cause of short-circuit in the winding of three-phase asynchronous motor is long-term overload operation, which makes the insulation aging. When the motor is in use, if the current is too large, single-phase operation, it will cause short-circuit between winding turns, short-circuit between winding, short-circuit between winding electrodes and short-circuit between winding and other phenomena. Here is a simple understanding with Senli Motor Xiaobian.

Motor has become an essential equipment in production, so how to use three-phase asynchronous motor in production to reduce energy consumption, save electric energy, so that it can play a benefit. The following is a simple understanding of some effective measures on motor energy saving with Senli Motor Xiaobian.

In the production process, the use of the motor will encounter various problems, three-phase asynchronous motor in use, if it can not start, we should deal with it in time, otherwise it will affect the subsequent production progress and cause losses. The following Senli motor Xiaobian will take you to a simple understanding of the reasons for asynchronous motors not to start.

Wire surface treatment is a very important process. At this time, we will use YLJ three-phase torque motor, because when the diameter of the drum gradually increases the product, it is very important to keep the tension rolling product unchanged during the entire production process, the tension is too large, the wire diameter is broken, or the thickness of the product is uneven, and the tension is too small, which will cause the winding to relax.

The YEJ brake motor has an electromagnetic brake at the tail, which also pulls in when the motor is energized. At this time the motor will not brake, the motor will be pulled in when the power is off, and the motor will be stopped by the spring. The two lines are connected to the two AC inputs of a bridge, synchronously input 380 volts AC with the two random inputs of the motor, and the direct output is connected to the brake excitation coil.

The YEJ brake motor consists of an ordinary three-phase asynchronous motor with an electromagnetic brake, which is installed on the extension end of the non-working shaft. We also call it an additional electromagnetic brake type three-phase AC asynchronous brake motor. Below, together with Senli Motor Xiaobian, a simple understanding of the working principle of YEJ brake motor.

Unwinding is also known as unwinding, unwinding, unwinding, etc. We generally use torque motors to complete this operation. In industrial production, it is sometimes necessary to transfer the product to the next process. In the transmission process, it is necessary to apply tension to the product in the opposite direction of transmission. At the same time, the linear speed and reverse tension of the product transmission are required to remain constant with the change of the barrel diameter, which requires the motor to have the characteristics of constant braking power.

Below we will use the most conventional three-phase asynchronous motor wiring method to explain to you, a motor wiring method is connected into a star or into a triangle, should be carried out according to the manufacturer's regulations, can be viewed from the motor nameplate. The head and end of the three-phase stator winding are set in advance by the manufacturer and must not be reversed arbitrarily.

The speed of the three-phase asynchronous motor is related to the number of poles of the motor. In the case of constant output power, the more poles, the slower the speed. Senli motor can do 2, 4, 6, 8 poles, can be customized according to the actual needs of customers, Senli motor provides diversified customization services: specifications customization, appearance customization, special shaft customization and color customization.

Because the design parameters of the motor are different, the occasions for its use are also different. Torque motor has soft mechanical characteristics, can achieve constant tension transmission, then what occasion to compare trial? Here is a simple understanding with Senli Motor Xiaobian.
