Electromagnetic speed regulating motor is composed of cage motor, electromagnetic slip clutch and DC excitation power supply (controller). Dc excitation power is small, usually composed of single-phase half-wave or full-wave thyristor rectifier, changing the conduction Angle of the thyristor, can change the size of the excitation current.

The motor that can be used by relying on single-phase AC is called a single-phase asynchronous motor, and its structure is simple. Easy to use, and a wide range of applications, relatively low noise, small interference to the radio system, often used in the power is not very large household appliances and small power machinery.

The previous article talked about the three classification methods according to the working power supply, structure and working principle, starting and operation mode. Today, Senli Motor Xiaobao briefly describes the five classification methods according to the use, rotor structure, running speed, protection type and ventilation and cooling mode.

In the first few articles, we understand the classification of several motors according to the working power supply, structure and working principle, starting, operation mode, use, rotor structure, running speed, protection type and ventilation and cooling mode. Today, continue to study with Senli Motor Xiaobian.

Today, Senli Motor Xiaobian first take you to a simple understanding of the classification standard of the motor, first talk about the three types of classification according to the working power supply, structure and working principle, starting and running mode:

At present, the city has introduced the intensity of power limiting measures, this trend will not change in a short time, in the double control of energy consumption downward, some high energy consumption, high pollution enterprises are forced to stop production, power limiting will be another problem facing the motor manufacturing industry.

The motor should be dried once it is flooded, whether it is a torque motor or a three-phase asynchronous motor, the way of water maintenance is roughly the same; There are many ways to dry, such as hot fans, light bulbs, etc., of course, if you can use a dryer, the effect is naturally better.

Variable frequency motor under unstable load conditions, has the function of adjustment, can achieve on-demand distribution, can better avoid energy waste, it can be combined with load changes to achieve different frequency conditions. Here is a look at the energy-saving effect of inverter motor with Senli Motor small edition.

Gridlock torque refers to the torque when the speed of the mechanical equipment is zero. Such as AC torque motor, AC three-phase asynchronous motor and other AC motors, in the blocked state, there is an AC voltage input, but the motor does not rotate state, is still able to produce torque.

Generally speaking, the motor will rely on inertial motion after cutting off the power supply, and then rotate for a while before stopping, and the lifting equipment such as hooks, or the lifting basket and other mechanical equipment can be accurately positioned; If it is a sudden power failure of the lifting equipment, the ordinary motor cannot guarantee the rapid stop of rotation, but the brake motor can meet the effect of rapid braking, the following is to understand together with Senli Motor Xiaobian.
