摘要:

We describe modifications made on a commercially available stepper motor to enable it to operate at liquid‐helium temperatures. The motor has a step angle of 6 deg and produces a torque of approximately 7×104dyn cm. When the motor is coupled to an 88:1 reduction gear, approximately 5×104ergs of heat are produced for each step.
