MEASUREMENT OF TORQUE IN MICROMOTORS

• Abstract:

  This paper describes a dynamometer developed for the measurement of torque of micromotors as a function of the rotational speed. The operating principle of the device is based on that of a typical viscometer. The shaft of the micromotor to be tested is coupled to a small cylinder, which is placed concentrically into a larger cylinder. The motor torque is transmitted from the inner cylinder to the outer one by means of a well-known viscosity fluid. A pneumatic cylinder supports the outer cylinder, so that the test is performed under free-friction conditions and the torque is determined by a lever arm in contact with a load cell.
