Constructing Stepper Systsems
However as a general rule hybrid stepper systems perform very well up to 800 RPM. From 800-1400 RPM you can expect to lose as much as 50% of the original torque depending on the motor. in on the axis requirements and ascertain a torque figure and RPM, from there we can match a motor and … Read Full Source

STEPPER MOTORS
The amount of torque produced by a stepper motor is often specified by its holding torque (the amount of torque needed to cause an energized motor to lose its position). For example, servo systems using a low inertia, hollow rotor DC brush motor can accelerate from a dead stop to 2,000 rpm in about one … Document Viewer
