YVPEJ electromagnetic brake variable frequency speed regulating three-phase asynchronous motor

Special motors for printing machinery are divided into main motors, paper feeder motors and dampening motors according to their functions. YVPEJ series electromagnetic brake variable frequency speed-regulated three-phase asynchronous motor is a main motor specially designed for printing machinery. It has excellent low-speed constant torque characteristics and braking characteristics. The YVPEJ series motor is composed of a variable frequency speed-regulated three-phase asynchronous motor, an electromagnetic brake and cooling Combined with a fan, the motor can be combined with various types of constant torque load inverters to form an AC variable frequency stepless speed regulation system. It operates with constant torque speed regulation in the range of 5-50HZ (or 6-6OHZ), and 50-100HZ ( Or constant power speed regulation operation within the range of 60-120HZ).

YVPEJ series motor technical parameters

The braking torque of the brake, the normal working air gap δ, and the maximum working air gap δ max are shown in the table below.

Brake release handle for 160 and below, brakes with release screw for 180 and above. The brake disc is a wearing part. When the disc is worn and the working air gap approaches δ max, a feeler gauge should be used to adjust the hollow bolts and installation screws in time to bring the working air gap to the normal value. If necessary, the brake disc should be replaced. (See brake instructions). When the brake is powered by AC 380V (220V), the motor outlet box is equipped with a rectifier module.
