NMRV/NRY Series Worm and Gear Motor

1.     Summery

NMRV Series Worm Gear Motor contains worm gear reducer and motor(Including three phrese AC motor,single AC motor,DC servo motor and DC PM motor).The square aluminum gearbox is manufactured based on GB1055588 cylindrical gear parameter.During the process, many advanced technologies are adopted.So it has compact structure, good appearance and excellent heatsink when runing.

This series motor has the following characteristics:smooth running, low noise, large transmission ratio and strange loadcapacity  and it may match with different kinds of motors for realizing speed adjustment.

2.Model Explanation

NMRY/NRY  063 - 40 – E –F – SZ/DZ - 71B5

1.     NMRY indicates motor and reducer is connected by flange and NRY indicates motor and reducer is connected by shaft coupling.

2.     063 indicates the center distance between worm and gear is 63mm in speed reducer.

3.     40 indicates the ratio of worm gear speed reducer.

4.     E mark indicates the double extension worm shaft. If there is no E mark, it means this kind motor has single extension worm shaft.

5.     F mark indicates the output flange. If there is no F mark, it means this kind motor doesn’t have output flange.

6.     SZ indicates the two way output shaft,while DZ indicates the two way output shaft.If there is no mark, it means the motor adopts hole output.

7.     71B5 indicates the motor housing No.and mounting model.
