Document Type and Number:
Japanese Patent JPS60501535
Kind Code:
A
Abstract:
A power control that delivers electrical power to a A.C. motor at a frequency which is controlled by the motor speed itself without the need for any separate speed sensing circuit. The power control accomplished this by allowing a small second current to flow from motor terminals of higher electrical potential to motor terminals of lower electrical potential, and then to provide means for the second current to cause current to flow from the power source through the motor terminals in the direction opposed to the motor terminal potentials thereby supplying electrical power to the motor.
