YZR-H Series Marine Three-phase Asynchronous Motor

Category

About product

The YZRE-H series motors are developed based on the YZR-H series, equipped with a DC electromagnetic brake, and fully comply with the requirements of the industry standard JB/T7077. In addition to inheriting the high overload capacity and strong mechanical durability of the YZR-H series, they offer the following advantages:

  • Adjustable braking torque to suit different working conditions;
  • Compact structure for easy installation and maintenance;
  • Convenient operation and flexible control;
  • Excellent braking performance with a built-in disc brake ensuring reliable stopping.

Product Detail

YZR-H Marine Motor with Wound Rotor

The YZR-H series motors adopt a wound rotor design and feature high overload capacity, superior mechanical strength, and reliable performance. They are especially suitable for driving various types of hoisting machinery, metallurgical equipment, and other devices requiring frequent starting and braking, such as marine windlasses, winches, cranes, and hoists. These motors are designed to meet the demanding conditions of marine and metallurgical applications, ensuring stable operation under short-time or intermittent duty cycles.

  1. Protection Class: The marine hoisting motor housing has a protection class of IP44, effectively preventing the ingress of solid objects and splashing water, ensuring safe and reliable operation in marine and port environments.

  2. Insulation Class: The motor adopts Class F insulation, providing excellent thermal resistance and insulation reliability, suitable for the frequent starting and heavy-duty operation of hoisting machinery.

  3. Terminal Box: The stator terminal box is located on the top of the frame, with wiring accessible from either side of the housing, offering flexibility for installation and easy maintenance.

  4. Transmission Method: The motor can be connected to the working mechanism via coupling or spur gear transmission. When spur gear transmission is used, the pitch circle diameter of the gear should not be less than twice the shaft extension diameter to ensure reliable and durable operation.

  5. Brush Holder and Carbon Brushes: The YZR and YZRE series motors are equipped with newly designed constant-pressure spring brush holders. As the brushes wear during operation, the contact pressure between the slip ring and the brushes remains constant, ensuring reliable performance and extended service life.

This motor can operate normally under the following conditions:

  • Ambient temperature not exceeding 40℃ (for general environments);

  • Installation site altitude not higher than 1000 m;

  • Capable of withstanding continuous mechanical vibration and shock;

  • Suitable for frequent starting, braking (electrical or mechanical), and reversing operation.
