cJunction box
The junction box is located at the top of the motor and is made into six terminals. The incoming line mode is a rubber-sheathed cable structure. Four bolt through holes connecting the box base and the machine base are arranged in the junction box. The junction box has a large space, meets the requirements of electrical clearance and creepage distance of voltage 1140V, and can also meet the requirements of convenient underground wiring operation in coal mines.The junction box has sufficient mechanical strength, and the connection between the terminal block sleeve and the box base adopts a threaded flameproof structure, which has good flameproof performance and is not easy to be damaged during maintenance, assembly and disassembly.The locking of the wiring bolt adopts a double nut locking structure, which can reduce the local heat at the connection between the external cable and the wiring bolt and improve the reliability of the connection between the external cable and the wiring bolt.According to different starting requirements, one wire inlet (suitable for direct starting of motor) and two wire inlets (suitable for Y-starting of motor) can be made respectively.

Bearing selection

The motor adopts motor-specific rolling bearings, which can effectively suppress the vibration and noise when the motor is running. The allowable temperature of the bearings (thermometer method) does not exceed 95 ºC
