Stepper Motor Brake YEJ2-250M-2 55 KW

YEJ Series Electromagnetic Brake Motors have features such as small volume, simple structure, strong universality, etc. This series of motors have low noise, reliable braking performance and are suitable for working conditions such as rapid stop, accurate positioning, reciprocating operation and sliding preventing. This series of motors adopt continuous working duty S1, which can also be derived to S3, S4 as per customers’ requirement. YEJ series motors can achieve rapid braking after power loss. The motors are widely used in machinery industries such as wind power yaw braking, machine tool, packing, woodworking, chemical industry, textile, construction.

Conditions of Use This series of motors can run continuously at rated power under the following conditions 1 Altitude: no more than 1000 meters 2 The ambient air temperature varies with the season, but does not exceed +40°C. Voltage frequency and working mode: Frequency: 50HZ, 60HZ Voltage: 220/380V, 380V/660V Connection method: Y connection method for power of 3 kW and below, △ connection method for 4 kW and above Insulation class: B class, F class Protection class: motor IP44, IP54 or IP55, brake part protection class is IP23 Note: For more requirements, imported bearings and drive fixed bearings can be used YEJ series electromagnetic brake motors are suitable for main shaft transmission and auxiliary transmission in various machinery requiring quick stop,

accurate positioning, reciprocating operation, anti-skidding. YEJ series electromagnetic brake three-phase asynchronous motor is suitable for the requirements of quick stop, accurate positioning, reciprocating operation, anti-skid and for main shaft transmission and auxiliary transmission in various machinery, such as lifting machinery, transportation machinery, packaging machinery, food machinery, printing Machinery, construction machinery, woodworking machinery, deceleration machinery, metallurgical machinery, forging machinery, etc.

YEJ brake motor is also called additional electromagnetic brake type three-phase AC asynchronous brake motor. How does the brake work? The following editor will briefly introduce the working principle of the YEJ brake motor brake.

The YEJ brake motor consists of an ordinary three-phase asynchronous motor with an electromagnetic brake, and the brake is installed on the non-working shaft extension end . The excitation current of the brake is generally direct current. According to different control requirements, it can be supplied by a separate direct current power supply, or an alternating current can be introduced from the motor terminal, which is converted into a direct current power supply after rectification.

YEJ brake motor brake can be divided into two types, one is to use the spring force of the brake to generate a braking force on the motor rotor when the power is not applied. After the excitation coil is energized, the electromagnetic force will The brake disc is disengaged from the friction plate fixed on the rotor shaft to eliminate the braking state, which is called power-off braking; the other is that there is no braking torque when no power is applied, the rotating shaft can rotate freely, but the excitation coil After the power is turned on, the braking force is generated, and the braking torque is applied to the rotating shaft, which is called power-on braking. The former is widely used.

Braking torque, called energized braking, the former is widely used. YEJ electromagnetic brake motor is also called additional electromagnetic brake type three-phase AC asynchronous brake motor, so how does the brake work?
