Torque motor is also called torque motor, with low speed and high torque characteristics, and we are familiar with the three-phase asynchronous motor principle is the same, can be divided into DC, brushless DC, AC these several. In order to improve the torque, it has more poles, let's look at a table:

Three-phase asynchronous motor is the most widely used motor in the current production, there are two ways of wiring methods, star wiring (Y) and triangle wiring (△), but what if the two wiring errors? The following Senli motor Xiaobian will take you to understand the next.

Three-phase asynchronous motor in the current industrial and agricultural production, can be said to be the main load equipment, but also one of the main loads in the power grid; In the selection of this motor, saving energy is of great significance, so today, we will look at the main aspects of choosing this motor with Senli Motor Xiaobian.

In the process of production and use of the motor, there will be various reasons for failure; The following Senli motor small series has collected some common faults and troubleshooting methods for torque motor work, only for reference, if there are questions or failures in use, you can contact the company's technical department in time to solve.

First of all, 3KW three-phase asynchronous motor and 3KW single-phase asynchronous motor, if only literally, are 3KW power, but the input voltage of the two is different, one is three-phase electrical input, one is single-phase electrical input; The relative working principle will also have a certain difference, if we do not consider other external and internal factors, in the same time consumption of electricity is the same, then their horsepower will be different?

Torque motor because of the use of different scenarios, so the mechanical equipment driven by its winding or transfer of material categories, specifications, etc., are also different, then the tension required will be different, generally by adjusting its torque, or within a certain range of variable speed, this operation we usually use to adjust the voltage imposed on its to achieve these requirements. So today, Senli Motor Xiaobian will take you to understand the common forms of voltage regulators.

The resistance of the torque motor is larger than the rotor resistance of the ordinary squirrel cage motor, but the operation principle of the two is actually the same, but the former uses a material with relatively high resistivity as the guide bar end ring of the rotor; Today, Senli Motor Xiaobian will take a shout to understand its principle.

Ac three-phase asynchronous motor can be used as a generator, as long as the rotor is rotating, the rotor rotation is driven by other energy, the rotor rotates in the stator's magnetic field; At this time, the rotor (that is, the closed circuit) is affected by the stator's magnetic field, which generates a current and becomes a generator.

The torque motor used in production sometimes produces noise, and the noise generated is a tricky thing to eliminate, which is usually used as a quality standard for assessing products. Today, Senli Motor Xiaobian will take you to analyze the causes of motor noise.

The three-phase symmetrical winding of the three-phase asynchronous motor will generate a rotating magnetic field with a speed of n1=60f/p in the air gap after the three-phase AC is connected. n1 represents the speed, f represents the frequency, the power supply frequency in China is 50Hz, p represents the number of magnetic poles, this is in pairs, 2P motor only 1 pair of magnetic poles.
