Y-series Marine Tunnel Thruster Motors

The Y-series marine tunnel thruster motor is a fully enclosed self-fan-cooled rat cage-type three-phase asynchronous motor for general use. The installation dimensions and power levels conform to IEC standards, the shell protection level is IP44, and the cooling method is IC411, continuous working (S1).

Y series marine tunnel thruster motor high efficiency, energy saving, high torque blocking, low noise, small vibration, safe and reliable operation. The Y 80 ~ 315 motor meets the Y series (IP 44) three-phase asynchronous motor technical conditions JB/T9616-1999. The Y355 motor meets the Y series (IP 44) three-phase asynchronous motor technical conditions JB 5274-91. The Y 80 ~ 315 motor adopts B-class insulation. Y355 motors employ F-class insulation. The rated voltage is 380V and the rated frequency is 50Hz. Power 3 kW and below is Y-join; The other power is △ connected. The motor operation site is no more than 1000m above sea level; ambient air temperature varies from season to season but does not exceed 40 ° C; Minimum ambient air temperature is -15 ° C; The average maximum relative humidity of the wet month is 90 per cent, while the average monthly minimum temperature is not higher than 25 ° C.

The motor has a shaft extension, which can be made into a double shaft stretch as the user requires, and a second shaft stretch that transmits rated power, but can only be driven by couplings.
