three phase ac electric motor 7.5hp

three phase ac electric motor 7.5hp

I. Product Application
RQQ series are soft start crane motor, which is used for electric single girder,double hoists girder, gantry cranes and other lifting equipment. It’s a new type integrated motor for both big and small Trolley .

 

II. Product Features
1. This soft start motor according to current driver’s dimensions, to optimize the design, integrated the soft start motor, reducer and the brake. Thereby improved the installation quality, reduced the assembly time, optimized installation program. Integration motor is with small size, light weight, easy installation and easy-maintenance, compact and beautiful structure.

2. This series soft start motor is equipped with YSE series dual-rotor soft start 3 phase asynchronous brake motor. F-class insulation, IP54 protection class. Motor housing is aluminum alloy. So it prevents the motor winding aging easily, extends the lifespan of the motor. Motor adopts cold-rolled silicon steel sheet, (which) enhances the output power, the motor heat condition,starting torque performance.It is much better than hot-rolled silicon steel sheet.

III. Operating conditions
1. Power supply: 50 ± 1% Hz, 380 ± 10%; -15 ℃ ≤ ambient temperature≤45 ℃. relative air humidity ≤85%, The working environment should be no explosion dust and non-corrosive.
2.Protection class IP54, insulation class F.
3.Work quota is S3-25%, 120 times per hour.
4. No rain and exposure , outdoor use should be packed with protective cover.
5.Motor should connect ground line, please refer to the power distribution regulations.
6. Before the motor installed on the device, please make sure the whole system has good and stable operating characters in the unloaded test.
7. After the driver installed on the device, please fill gear oil according to the note that posted on the driver. 8. Automatic braking when power off.
