Abstract

PURPOSE:To generate the constant torque over a wide range of temperatures, by controlling the speed of a motor by the detection signal sent from a magnetism- sensitive element that detects a fluctuation of magnetic flux caused by a drift of temperature. CONSTITUTION:A constant torque generator 8 includes the 2nd rotary disk 16 that generates the constant torque and the 1st rotary disk 17 that receives the torque T having the same absolute value as the disk 16. The magnetic flux corresponding to the eddy current I caused within the disk 17 is detected by a magnetism-sensitive element 21. The angular speed omega of a motor 9 is controlled by means of the detection signal Vf supplied from the element 21. As a result, the disk 17, i.e. the disk 16 can generate accurately the constant torque over a wide range of temperatures.
