Product Detail

YVF Series Marine Motor Cooling Method

marine YVF-H Series Motors

The YVF-H series motors are equipped with built-in fans, providing natural ventilation and basic cooling. They are suitable for marine or industrial applications that do not require long-term low-frequency operation. Under medium to high-frequency operation, these motors maintain effective heat dissipation, ensuring stable and efficient performance.

YVFF-H Series Motors

The YVFF-H series motors use independently powered axial fans for forced air cooling, significantly enhancing heat dissipation. This design allows the motors to operate continuously at low frequencies for extended periods, making them ideal for ship auxiliary equipment, pumps, fans, and hydraulic machinery requiring long-term low-speed operation.

Y2VF Series Adjustment Speed Three-Phase Inductive Marine Motor

  1. The motor is designed for continuous duty operation (S1).
  2. The rated voltage of the motor is three-phase 380V, with a rated frequency of 50Hz. The rated voltage and frequency can also be customized according to user requirements.
  3. The motor offers a wide speed regulation range of 5(3)–100Hz with stepless control. From 5(3)–50Hz, it provides constant torque regulation, and from 5(3)–100Hz, constant power regulation. Under vector control, the adjustable speed range can be further extended.
  4. Strong overload capacity: the motor can withstand 160% of the rated torque for up to one minute.
  5. Excellent low-speed performance: torque remains smooth at low speed without crawling.
  6. The insulation class of the motor is Class F, with insulation designed to withstand the high carrier frequency voltage output from frequency converters.
  7. Protection class: IP55 (axial fan part IP44).
  8. Wiring method: for motors up to and including 55kW, Y-connection is adopted; for motors above 55kW, delta connection is used.
  9. Structurally, the installation dimensions of the Y2VF series are identical to those of the Y2 series, ensuring compatibility and ease of selection. The motor adopts a unique cooling structure with an independent axial fan, ensuring that the temperature rise does not exceed the permissible limit during long-term low-frequency constant-torque operation.
  10. The motor is 4-pole by default, but other pole numbers can be designed according to user requirements.
