For driving a spindle or for use in a linear actuator? Steppers are the motor of choice for linear actuators, even in the big professional CNCs. For driving a spindle, 3 phase motors dominate.

Maybe some of you can can recommend high torque (above 1 N*m), low speed (up to 200RPM) motor and driver? The main problem that I want to have full torque with constant speed on all range of speeds. E.g . 1 N*m ot torque at 5RPMs and the same torque at 200RPMs.
