Title:
LOAD DEVICE OF ERGOMETER
Document Type and Number:
Japanese Patent JPS6016170
Kind Code:
A
Abstract:
PURPOSE:To obtain a constant torque without any complicated control by using an iron steel material which contains carbon and silicon contents in the prescribed values or lower for a material of an outer rotor. CONSTITUTION:A load device of an ergometer has an outer rotor 5, an inner stator 7, a plurality of exciting coils 8 provided in the inner stator, and a current source for energizing the coils 8. The rotor 5 is formed of an iron steel material which contains 0.12% or lower of carbon content and 0.35% or lower of silicon content. Further, a current command signal is generated in response to the output of instructing means in a circuit 9, and a current supplied to the exciting coils is controlled in response to the output of the current command signal. Thus, excellent constant torque property can be obtained.
