Torque Test Bench

Postby wikicheema » Thu Apr 14, 2016 5:21 am

Dear Sales,

I am looking for servo motor for variable torque application.

Main characteristic are given below.

1. Rotation 0-90 degree and 90-0 Degree.
2. Out speed <0.25 Rpm
3. Torque range 50 Nm to 10,000 Nm

I have one question regarding servo motor operation. That is following.

1. Will toque vary while depending on the load at constant speed?

I want variation in output toque so that I can measure the actual torque required to rotate the shaft . I am also aware of the fact that this torque is very high and will need a gearbox. Also please propose suitable servo gearbox.

Looking forward to hearing from you.

Hi wikicheema,

Our NX series servo motor systems offers position control, speed control, tension control and torque control operating modes. The torque control mode would meet your requirement. However, with the biggest motor (1/2HP, 1HP) and highest gear ratio (25:1), we are nowhere near 10,000 Nm. We can output 47.8 Nm rated / 143 Nm max limited torque with our 1HP model, and 25.7 Nm rated / 77.2 Nm max limited torque with our 1/2HP model.

Please see links below for both models:
1HP: http://catalog.orientalmotor.com/item/a ... 75as-j25-3
1/2HP: http://catalog.orientalmotor.com/item/a ... 0as-ps25-3

Our DG2 series rotary actuator systems offers 50 Nm rated permissible torque. Please see below link:

We don't offer anything for 10,000 Nm. It wouldn't be easy even with external gearing.

Servo motors draw only the current it needs to move the load at the set speed. At constant speed, the load torque typically doesn't change (unless there's variable friction), so the current shouldn't change. Torque is proportional to current, so torque shouldn't change either.
