Abstract
A motor controller is disclosed. A motor controller according to one embodiment of the present invention comprises a first electronic control unit (ECU) which comprises a first substrate having a first length and controls a motor, a connector which is connected to one end portion of one longitudinal side of the first substrate to transmit power and a signal to the first ECU, a second ECU which comprises a second substrate having a second length shorter than the first length and including one surface facing one surface of the first substrate and controls the motor, and a connection element which is disposed to connect the first ECU and the second ECU in a circuit and transmits the power and the signal to the second ECU.
Claims17
A motor controller comprising:
- a first electronic control unit (ECU) which comprises a first substrate having a first length and controls a motor;
- a connector which is connected to one end portion of one longitudinal side of the first substrate to transmit power and a signal to the first ECU;
- a second ECU which comprises a second substrate having a second length in a longitudinal direction of the motor shorter than the first length of the first substrate in the longitudinal direction of the motor so that at least a part of the connector connected to the first substrate is disposed at a space formed by the shorter second length of the second substrate in the longitudinal direction of the motor than the first length of the first substrate in the longitudinal direction of the motor, wherein the second ECU includes one surface facing one surface of the first substrate and the second substrate is configured to control the motor;
- and
- a connection element which is disposed to connect the first ECU and the second ECU in a circuit manner and transmits the power and the signal to the second ECU.
