Since the 1970s, AC torque motors have been used in winding devices such as film development, light industrial chemical fiber, textile, cable, plastic and paper making. Speed control is achieved through two methods: speed feedback and control tension size of the speed measurement motor. Today, Senli Motor Xiaobian will take you to understand its classification:

The previous article we talked about torque motor manufacturers lathe processing, rotor finishing, stator coil winding processing process requirements, Senli motor 19 years to focus on the field of motor, the old motor factory is the source of independent research and development manufacturers, the following Senli motor Xiaobian for you to share today's content:

A motor with two operating speeds. Two-speed motor belongs to the three-phase asynchronous motor pole change speed regulation, is to change the stator winding connection method to change the stator rotating magnetic field pole number, so as to change the motor speed.

Do you know how many steps it takes to produce a torque motor? Manufacturers in the production of motor, have a set of processes and processes, today we simply understand the production of parts processing requirements:

The ordinary three-phase asynchronous motor can be equipped with a frequency converter, but the fan of the ordinary motor is installed on the motor shaft, so when the motor speed is low, the heat dissipation effect will become worse; According to the constant frequency and constant voltage design, it can not fully adapt to the requirements of frequency conversion speed regulation, but the frequency conversion motor can solve this problem. The difference between the variable frequency motor and the three-phase asynchronous motor is that the cooling fan of the former is not fixed on the shaft of the motor, but is powered by the power frequency power supply alone

After purchasing torque motor products, some customers do not know how to make the motor maintain good performance in subsequent use. Here we need to do regular maintenance and cleaning of the motor, the following and Senli motor small series together to simply understand the motor in the cleaning and maintenance to pay attention to matters.

We have previously understood the wiring method of low-power three-phase asynchronous motor during single-phase operation; So how to choose the right capacitor for the single-phase running motor in the production operation, today's Mori motor editor will tell you how to choose the capacitor for single-phase running.

Stepless speed regulation means that the speed of the motor can be evenly and smoothly changed when it adjusts the speed of the working mechanical process. The mechanical characteristics of the torque motor are very soft, when the load increases, the speed of the motor decreases, the output torque increases, and the output torque is proportional to the square of the voltage. If the load is fixed, the speed of the motor will change with the voltage.

In production operations, sometimes it is necessary to use three phases to do single-phase operation; Low-power three-phase asynchronous motor can not only do three-phase operation, but also can do single-phase operation; They're wired differently. Today, let's take a look at how to connect low-power motors under 750w single-phase operation:

During production, mechanical problems are often encountered; When the torque motor fails, we should ask technicians to repair it and carefully disassemble it, then today the Senli Motor editor will talk about the problem that the torque motor cannot start and the solution: If the power is turned on during the use of the torque motor, but the motor cannot start normally, there may be the following reasons:
