Abstract
The electrical contact type governers are widely used as the velocity control mechanisms for micro-motor. The chief factors effective for the behaviour of this type governer are composed of (1) vibration of its pendulum system, (2) inductance of the motor coil, (3) electrical resistance of the contact point, and also (4) vibration of the motor shaft.
In this paper, are mainly studied by theoretical treatment of the problems concerning to the rotation velocity control accompanied with the vibration phenomena of the governer pendulum system. For the respective variations of the source voltage and the load applied to the motor, both the average rotation velocity of the motor and the pendulum amplitude. of the governer system are able to be calculated quantitatively when both of the electric elements of the motor and the constructive elements of the governer are given. The theoretical results thus obtained are also confirmed to be reasonable by experiments.
