JY series special motor for speed reducer

The three-phase asynchronous motors for speed reducers are a series of high-efficiency and energy-saving three-phase asynchronous motors specially developed by our company in accordance with the characteristics of speed reducers. The energy efficiency grade is in accordance with the energy efficiency regulations of GB 18613-2020, "Energy Efficiency Limiting Value and Energy Efficiency Grade of Electric Motors

1）The three-phase asynchronous motors for speed reducers are a series of high-efficiency and energy-saving three-phase asynchronous motors specially developed by our company in accordance with the characteristics of speed reducers. The energy efficiency grade is in accordance with the energy efficiency regulations of GB 18613-2020, "Energy Efficiency Limiting Value and Energy Efficiency Grade of Electric Motors

2）The motor uses a new type of ventilation fan heat housing and cooling fan, which is based on the principle of fluid mechanics and uses unequal slices, and the heat sink is reshaped according to the principle of grade difference, expanding the surface heat dissipation area by about 11%.

3）The shaft material is tempered, the oil seal is quenched at high frequency, and the R-angle transition is adopted at the motor shaft extension step to effectively avoid the stress concentration, and the motor oil seal installation is chamfered to effectively avoid the oil seal damage caused by the oil seal assembly.

4）Motor interchangeability, the same seat number, motor flange can be interchangeable at will, motor junction box can be rotated in any of the four directions, greatly meet the individual requirements of customers

5）The motors are all F-class insulated motors, safe and reliable, long life

6）Directly connected braking motor, can quickly brake, accurate positioning, prevent slippage, etc., can meet the different requirements of the use of customers and Operating conditions

7）Directly connected to the frequency conversion motor using special electromagnetic design, through the frequency converter can be infinitely variable speed control of the motor, wide range of speed regulation, small vibration, easy to achieve a variety of automatic control features
