YZRE-H series winding rotor marine three-phase asynchronous motor also known as YZRE series electromagnetic brake motor consists of a YZR-H series motor plus a DC electromagnetic brake. Complying with the provisions of the existing machinery industry standard JB/T7077, This series of motors have the characteristics of large overload capacity, high mechanical strength, compact structure, adjustable brake torque, and easy control and maintenance. Suitable for short or intermittent operation, frequent start, braking, sometimes overloaded lifting and driving and braking on translation and lifting mechanisms in metallurgical equipment. The motor is equipped with a disc brake so that the motor has a good braking effect. The YZRE-H series motors are brush-held with the latest design of constant voltage springs, and the pressure between the collector ring and the brush can remain the same when the brush is worn out in operation.

The working systems of this series of motors are divided into eight types: S2, S3, S4, S5, S6, S7, S8, S9
S340% (i.e. working at S3, 40% load duration, 10 minutes per cycle). The following are several of the most commonly used working systems for this series of motors.
Operating at a given time under a constant load, the motor is not sufficiently thermally stable during that time, and then downtime and energy loss are sufficient for the difference between the temperature of the motor and the cooling medium to be within 2K.
Run by a list of the same working cycles, each including a constant load run time and a downtime and outage time. In this type of work, the start current per cycle does not have a significant effect on heating.
Run by a list of the same working cycles, each including a period of startup time with a significant impact on heating, a period of constant load run time, and a period of downtime and outage time.
Run by a list of the same working cycles, each including a start time, a constant load run time, an electric brake time, and a downtime and outage time.
