Title:
BRAKING DEVICE
Document Type and Number:
Japanese Patent JP2023119254
Kind Code:
A
Abstract:
To provide a braking device that can suppress electric currents corresponding to back electromotive force generated in an electric motor when reducing load torque and loss torque applied to a pump from flowing into a power supply of the electric motor.SOLUTION: A braking device 10 comprises: a pump device 30 having an electric motor 31 and a pump 41; a first liquid passage 15 through which brake liquid is ejected from the pump 41; a second liquid passage 16 connected to the first liquid passage 15; a check valve 17 provided at a connection part between the first liquid passage 15 and the second liquid passage 16; and a control device 70 that controls the electric motor 31. The control device 70 has a driving circuit 71 including a plurality of switching elements 72a and 72b and a control part 81. The control part 81 starts closed-loop formation processing for forming a closed loop by turning on only some of the plurality of switching elements 72a and 72b when the electric motor 31 is rotating, in order to stop driving of the electric motor 31.SELECTED DRAWING: Figure 1
