GLOSSARY AND DEFINITIONS Detent or Residual Torque The torque required to rotate the motor’s output shaft with no current applied to the windings. A drive technique to accelerate a given load from a low step rate, to a given maximum step rate and then to decelerate to the intial step rate without the loss of steps. Drives Term depicting the external electrical components to run a Stepper Motor System. This will include power supplies logic sequencers, switching components and usually a variable frequency pulse source to determine the step rate. Dynamic Torque The torque generated by the...
