High speed stepper motor

Hello. Can someone help me with an exempel of high speed drive of stepper motor, please? Need about 1000 rpm. Motor have 200 steps/rpm.

Thank you for help.

I think it depends on your motor and your application. I am not really a specialist, but I will give you an example to illustrate. I had a project where I wanted torque and speed. I was able to reach the speed with insufficient torque with one driver that came with the motor. I believe it was designed for direction control rather than speed control. I had to upgrade for higher specs driver to get the required torque. For people to be able to help, you may share your motor specs and what kind of application do you need it for.

What is the project that requires 1000 RPM? It is much easier to give useful advice when we know the context of the question.

Generally stepper motors are used for precision rather than speed. Wen choosing a motor you also need to know how much torque is required.

The useful torque of a stepper motor falls off rapidly as speed increases and the better motor manufacturers show graphs of the performance of their motors.

For high speeds it is usually necessary to drive the motor with a high voltage.

Why not use a DC motor they are much easier to control and with feedback you can get very close.

For higher performance from a stepper you need:

a) a low-resistance, low-inductance bipolar stepper. (Its the inductance that matters really) b) a high DC supply voltage c) a stepper driver capable of the required motor current spec and supply voltage. Stepper drivers are chopper-based constant current converters.

Basically performance is proportional to supply voltage / winding inductance / motor current Performance can be greatly affected by resonance issues causing miss-stepping, so damping and microstepping are important.

At 1000 RPM it sounds like angular position and velocity control is more appropriate than a stepped shaft angle so you might want to find out if synchros and resolvers are more appropriate.

Maybe not, lead-screw based CNC machines commonly do things this way as they need both fine position control and fast rapids.
