YCTJ-H Series Three Phase Squirrel Caged Induction Motor for Side Thruster

Introduction

Introduction
The YCTJ-H series of three phase marine induction motor for side thrusters is a completely enclosed, fan-cooled induction motor which works for power supply systems in all kinds of ships. The motor is the side thruster radiator and has a low starting current and high starting torque.

Construction
1. IP44 or IP23 protection rating
2. Material: HT200 cast iron frame with cooling ribs
3. Cylindrical shaft extension
4. Terminal box conforms to IEC IEC60034-8.The electric clearance is no less than 8mm and the creepage distance is no less than 12mm. Another binding post in the terminal box functions as a grounding connection.
