Motor controls |
摘要 |
An electrically actuated shifting mechanism includes a reversible rail select electric motor and a reversible in-gear electric motor. Three groups of switches are provided to effect one-at-a-time operation of the motors with a center group of switches being used to effect operation of either the rail select or the in-gear motor and to determine the direction of operation of the motor. In one embodiment of the invention, the motor control circuitry also controls the operation of a main clutch motor. Four groups of switches are used to effect operation of the in-gear, rail select and clutch motors in desired directions. Pulse width modulation is used to effect simultaneous and out-of-phase operation of the in-gear and main clutch motors.
