Three Phase Motor Mitsubishi SF-PRO Series
Can be use safely outdoors, even under weather conditions such as rain, wind, snow, etc.
- Waterproof performance (IP44 Degrees of protection)
Passed the water spray test for compilance with JIS C 4034-50, so it can be securely used outdoors.
The main parts of the motor are the same as of SF-PR type, but in order to provide stable operation even under severe outdoor conditions, such as wind, rain and snow, etc. special consideration is given to the following.
- Shaft through part Both the load side and the anti-load side are provided with a fringer that rotates together with the shaft so as to prevent water leaking inside the motor. In addition, an end cover is mounted to the load side to further improve the waterproofing. * On the vertical flange and horizontal flange type motors, fringer is provided only on the anti-load side. Note that the shaft through part does not have a waterproof structure since the load side is incorporated into the mating machine.
- Terminal box Terminal boxes with frame numbers from 80 to 180 are made of steel plate, and those with number 200 or higher are made of cast iron. To ensure waterproof structure, a gasket is provided between the base and the cover. Terminal block connection method is used for frame numbers 80 to 132, and lead wire connection method is used for frame numbers 160 and higher. Also, since the external cable entry port is parallel pipe threaded, conduits and watertight cable glands can be installed. * When changing the direction of the cable entry port, be sure to firmly seal the piping so as to prevent the ingress of water, dust, etc.
