(OP)
Hi all,

When you shift the speed of a PMDC motor using a gearbox, does the torque-speed characteristic of that particular motor also change or will it be still the same curve but with a different operating point?

Thanks in advance
Hadi

RE: gears and motors

The torque- speed curve  at the motor shaft remains the same. Obviously , at the output shaft the torque is increased by the gear ratio and the speed is reduced by the same ratio.

RE: gears and motors

Be careful with the gearbox efficiency. It will reduce the torque.
