Abstract

PURPOSE: To smoothly start a machine with varied starting loads, by gradually reducing a secondary resistance in comparison of a command value of a linear commander with a detection signal of a tachogenerator.
CONSTITUTION: When an operation switch 2 is contacted in, a notch of a controller 3 is progressively advanced by a timer 4 to start a motor 1. A switch S is turned on by the output from a speed generator TG, a command value of a linear commander 5 is gradually increased, a value of the tachogenerator may be less than the command value. At this time, the notch of the controller 3 is advanced by one step to increase the speed. Therefore, a starting time can be maintained substantially constant regardless of the load and moment value.
