Claims

[Scope of utility model registration request]

When switching the controlled DC motor between at least three modes: forward rotation, reverse rotation, and short circuit between the terminals of the motor, a binary control signal with a different number of bumps and a combination of level sizes is generated in accordance with the switching. A rotation control circuit for a DC motor that is supplied in parallel to a motor controller and controls the motor connected to the output of the motor controller to enter the mode according to a combination of the plurality of binary control signals. When the input of the motor controller is switched from the forward direction rotation (reverse direction rotation) mode to the terminal short circuit mode, a binary control signal corresponding to the terminal short circuit mode is input and the level is maintained for a predetermined period of time. A rotation control circuit for a DC motor, comprising a circuit that inverts the signal to a binary control signal corresponding to the reverse direction rotation (forward rotation) mode, and then converts it to a binary control signal corresponding to the terminal-to-terminal short circuit mode.
