- Brief Introduction
The full name of YEJ motor is: YEJ series electromagnetic three-phase ac brake motor (referred to as: YEJ series electromagnetic brake motor), which is a three-phase asynchronous motor with fully enclosed, self-fan cooled and squirrel cage type DC electromagnet brake. It is in Y series. A DC disc type electromagnetic brake is added between the rear end cover of the motor and the fan, which is a derivative series of the Y series.
- Applied Range
Applicable to all kinds of machinery that require electromagnetic three-phase ac brake motor, accurate positioning, reciprocating operation, frequent starting and braking, as the main equipment for auxiliary transmission and auxiliary transmission.
For example: electromagnetic three-phase ac brake motor, rubber chemical machinery, metal processing machine tools, packaging machinery, woodworking machinery, food machinery, chemical machinery, textile machinery, construction machinery and gear reducers.
Reliable electromagnetic three-phase ac brake motor, adjustable braking torque, non - axial rotor movement, easy to use .
- Standard Type
The motor conforms to JB/T6428--92<YEJ series (IP44) electromagnetic braking three-phase asynchronous motor technical conditions (frame size 80-225) >Requirements.
Rated voltage of electromagnetic three-phase ac brake motor is 380V, rated frequency is 50HZ, protection grade of enclosure is IP44, brake is IP23, cooling method is IC411, the reference working system is continuous working system SI, and the insulation grade is class B.
- Principle and Structure
The DC disc brake of the YEJ type electromagnetic three-phase ac brake motor is mounted on the end cover of the non-shaft end of the motor. When the brake motor is connected to the power supply, the brake also works at the same time.
Due to the electromagnetic attraction, the electromagnet attracts the armature and compresses the spring, and the electromagnetic three-phase ac brake motor is The armature and end cover are disengaged and the motor starts to rotate. When the power is turned off, the brake electromagnet loses the electromagnetic suction force, and the spring pushes the armature to press the brake disc. Under the action of the friction torque, the motor immediately stops rotating.
- Mounting Mode
In order to further understand the defects in motor operation, check test can be done before disassembly if possible. For this purpose, the electromagnetic three-phase ac brake motor with load test run, detailed inspection of each part of the motor temperature, sound, vibration and other conditions, and test voltage, current, speed, and so on, and then disconnect the load, a separate no-load inspection test, measurement of no-load current and no-load loss, make a record.
