Abstract
The present invention provides an electro mechanical brake (1) comprising an electrical actuator (2) which can simplify the structure of the electro mechanical brake (1) by integrating a control module (120) into a motor housing (11). The electrical actuator (2) may comprise a motor housing (11), a motor (110) provided inside the motor housing (11), and a control module (120) for controlling the motor (110), wherein the control module (120) is inside the motor housing (11).
Claims37
An electrical actuator for an electro mechanical brake, comprising:
- a motor housing;
- a motor provided inside the motor housing;
- a control module for controlling the motor, wherein the control module is inside the motor housing, the control module comprising at least a first printed circuit board provided with a control circuit for controlling the motor, a support element for holding the at least first printed circuit board, and wherein the at least first printed circuit board and the support element each have an annular shape with a center through-hole through which a drive shaft of the motor may be extended;
- and
- an electromagnetic brake fixed on the support element, wherein the electromagnetic brake is configured to generate a brake torque to stop the rotation of the drive shaft of the motor.
