Abstract
Provided is a dynamic brake device having a structure in which vibration of a switch part is not easily transmitted to a resistance part. This dynamic brake device is connected between a motor, and a motor drive device that drives the motor. The dynamic brake device comprises: a resistance unit that is attached to a first attachment surface and converts rotational energy of the motor into thermal energy; and a switch unit that is attached to a second attachment surface and switches the flow direction of current so as to cause a short circuit between the terminals of the motor via the resistance part. The first attachment surface and the second attachment surface are not positioned on the same plane.
Claims7
A dynamic brake device connected between a motor and a motor drive device for driving the motor, the dynamic brake device comprising:
- a resistor unit attached to a first attachment surface and configured to convert rotational energy of the motor to thermal energy;
- and
- a switch unit attached to a second attachment surface and configured to switch a flow direction of a current so that terminals of the motor are short-circuited via the resistor unit,
- wherein the first attachment surface and the second attachment surface are not positioned on the same plane.
