Motors used in winding equipment usually require fixed tension and fixed speed; However, when the winding operation is carried out, its diameter will gradually increase, so in order to ensure a fixed tension and speed, we now generally apply a torque motor to carry out this operation, because the motor used needs to meet the characteristics of gradually slowing down and increasing torque when the diameter is larger, and the torque motor is just enough to meet this characteristic.

The general variable frequency motor is derived from the driven squirrel cage three-phase asynchronous motor, and its additional load runs continuously within the range of 10%-100% extra speed, and the temperature rise will not exceed the allowable value of the calibration; It can also be driven by the inverter to achieve different speed and torque to adapt to the needs of load changes.

In the front, Senli Motor Xiaobian has briefly introduced some reasons for the frequency conversion motor to produce overcurrent, and today, Senli Motor Xiaobian will take you to understand the disposal method of tripping and tripping during operation when the overcurrent is generated.

Frequency conversion motor in the speed up the phenomenon of overcurrent, will cause the load inertia is large, if the speed up time is set to be short, then in the process of frequency conversion motor speed up, the frequency converter operation efficiency will rise quickly, synchronous speed will rise, but the rotor speed will be due to the load inertia can not keep up, which will cause the speed up current is too large.

The frequency conversion motor adopts the speed regulation method of "special frequency conversion induction motor + frequency converter", which can greatly improve the degree of mechanical automation and the efficiency of production, and the equipment is also developing in the direction of miniaturization. Today, Senli Motor Xiaobian will take you to understand about inverter motor overcurrent protection.

The previous small series of Senli motor briefly describes some hazards related to the three-phase asynchronous motor phase-to-phase failure; It is not difficult to find that the key to control the inter-phase insulation fault will involve a lot; If there is a problem, it is easy to cause the motor to burn, so the selection of insulating materials is also very important.

Interphase fault refers to the three-phase winding interphase short circuit or breakdown; During the processing of fixed rotor windings of three-phase asynchronous motor, the general motor manufacturers will check the insulation of the windings one by one to ensure the quality; Shengzhou Senli Motor has a complete testing process, the motor products to take full inspection factory to ensure that "unqualified products" do not flow out, can provide a complete quality test report.

The casing insulation damage of the winding connection line or the lead line of the three-phase asynchronous motor will also cause an interphase short circuit, which is a typical problem at the end of the winding. When the three-phase asynchronous motor manufacturer produces the winding, the phase and phase are insulated through the insulation casing. If the length of the casing is insufficient or the casing is damaged, it will cause an interphase insulation failure.

Shengzhou Senli Motor production YLJ series torque motor, belongs to a three-phase asynchronous motor, is a special motor with soft mechanical characteristics and wide speed range, Senli torque motor product frame distribution from 63 frame -112 frame, according to different operating speed requirements, made of 2,4,6, 8,10 poles, up to 20N.m.

There are many manufacturers producing AC torque motors. Torque motors have winding characteristics and can achieve constant tension transmission, which are generally used for winding or winding operations. If it is a wholesale purchase, it is recommended to purchase a prototype or go to the torque motor manufacturer's factory for field inspection.
