Three Phase Motor MITSUBISHI SF-PRP Series
Dust & Water jet proof performance (IP55 Degrees of protection)
Passed the dust and the water spray test for compliance with JIS C 4034-5, so it can be used with confidence in locations exposed to large quantities of water.
The main parts of the motor are the same as SF-PR, but in order to provide stable operation under even more severe conditions than those of the outdoor type, special consideration is given to the following
- Shaft through part Both the load side and the anti-load side are provided with a fringer or V-ring that rotate together with the shaft so as to prevent water leaking into the motor. In addition, end covers are mounted on the load side and anti-load side to further improve the dust & water jet proofing. * The vertical flange type motor has a fringer or V-ring mounted on the anti-load side, while the horizontal flange type motor has a fringer or V-ring and end cover mounted on the anti-load side. Note that the shaft through part does not have a waterproof structure since the load side of the vertical flange and horizontal flange type motors 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 complete dust & water jet proof 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.
- Mating part Liquid gasket is applied to the frame and bracket mating section to improve the dust & water jet proof performance. Reapply the liquid gasket when disassembling and reassembling the motor.
- Installation method Dust & water jet proof performance is provided in the standard installation direction shown in the dimensional drawings; inquire in the case of non-standard installation.
- Coating Coated with paint that is excellent in weather resistance, saltwater resistance, and chemical resistance.
