Structure Description

1 Cooling method of the motor: The cooling method of the motor is IC411, self-fan cooling.
2 Protection level of the motor: The protection level of the main housing of the motor is IP55, and the terminal box is IP55 (see GB/T4942.1).
3 Transmission method of the motor: The motor has a cylindrical shaft extension at one end, which rotates by means of an elastic coupling or spur gear.
4 The main housing material of the motor is made of steel plate, which has high impact and collision resistance. The other housing parts are made of gray cast iron or steel plate not less than HT250.
5 The motor adopts F or H grade insulation system and undergoes special process treatment, which has good electrical, mechanical, moisture-proof and thermal stability.
6 The motor rotor adopts cast aluminum structure, and the rotor runs smoothly, with low vibration and low noise.
7 The motor adopts rolling bearings specially designed for motors, and the bearings are of well-known brands. The bearing structure is designed with non-stop injection and oil discharge devices.
