In general, mechanical equipment that needs fast braking and braking needs will be applied to three-phase AC braking motors, such as transport machinery, packaging machinery, textile machinery and other transmission machinery.

During the operation of the motor, there are two kinds of heating phenomenon: the whole machine heating and local heating. The following Senli motor Xiaobian will take you to a simple analysis of the reasons for the heating failure of three-phase AC asynchronous motor.

We know that the brake motor has a braking, positioning function, the speed of the brake motor is selected according to the production machinery requirements, Senli motor can customize the product according to the actual production needs, to meet the production, equipment and personnel needs, and we can carry out diversified customization.

In the first part, we understand some common starting methods of three-phase asynchronous motors, and give a simple description of direct starting and autotransformer step-down starting methods. Today, Senforce Motor Xiaobian will take you to a simple understanding of the two methods of Y-△ step-down starting and frequency converter starting.

The production of machinery and equipment is inseparable from the power of the motor. Nowadays, the industrial machinery transmission technology continues to upgrade, and the special indicators of the motor require continuous new concepts, so that the motor products continue to expand in industrial automation. Some special transmission requirements of the machinery, there will be non-standard motor customization needs, most of the non-standard customization has the following two situations.

Brake motors have high precision positioning requirements. As a brake motor should have: rapid braking, accurate positioning, reliable, the brake system can be exchanged applications, the layout should be simple, replacement and maintenance of light characteristics. Many manufacturers require brake motors to control motor inertia, to reach the required accurate positioning, to achieve automatic work of the machine.

In the practical application process of YEJ brake motor, there are many methods of speed change and speed regulation. For example, through different combination connection methods of windings, you can obtain a total of 3 speeds of 2, 3 and 4. The speed change of this speed regulation method is different, and it is only suitable for some special applications, and can only achieve the purpose of large-scale coarse adjustment.

Senli Motor, 19 years focus on the development and production of motor. If necessary, you can search the factory name "Shengzhou Chaoli Electric Appliance Factory" on 1688, or leave a message online, we will have business staff to contact you, you can also contact us directly 0575-8378-1127.

The application of protective measures for motor products can not only ensure the long-term stability of the motor, but also effectively protect the safety of personal property. The protection link is an indispensable part of all automatic control systems, such as three-phase asynchronous motors, torque motors and other products, will add short-circuit protection measures, so the following and Senli motor Xiaobian together with a simple understanding of it.

The stator winding series resistance starting is carried out at the sacrifice of starting torque, and is only suitable for starting under light load or no load. Today, Senli Motor Xiaobian will take you to understand about the rotor series resistance or frequency sensitive resistance starting mode of three-phase asynchronous motor.
