Abstract
The electrical circuit between the power supply line and each motor or motor pair has an apparatus for re-transferring power from one mechanically driven and/or electrically braked motor to another of the motors. This apparatus includes a levelling or equalizing circuit and a plurality of back coupling devices such as diodes arranged in opposition in series. Each back coupling device electrically connects the intermediate DC circuit loosely to the levelling circuit. Upon braking of a motor, the power flows back through the associated intermediate circuit and then via the back coupling devices and levelling circuit to the other motors.
Claims10
In combination,
- a plurality of motors for a spinning machines,
- an AC power supply line for supplying power to said motors,
- a plurality of electrical circuits, each said circuit connecting at least one of said motors to said AC power supply line and including a rectifier connected to said power supply line, an intermediate DC circuit, and means for converting DC to AC, and
- an apparatus for re-transferring power from at least one of said motors to another of said motors in response to mechanical driving and/or electrical braking of said one motor, said apparatus including a power equalizing circuit, and bi-directional coupling devices electrically connecting each intermediate DC circuit loosely to said power equalizing circuit.
