Abstract: The present disclosure relates to a motor rotor control device and method capable of reducing noise caused by the alignment of a motor rotor, and securing stability of staring a motor.
The motor rotor control device in accordance with an embodiment of the present disclosure includes a motor having a rotor; an inverter for supplying a three-phase alternating-current voltage to the motor; and a control unit for estimating the initial location of the rotor upon the initial driving of the motor, correcting the location of the rotor by a predetermined angle from the estimated initial location, and then driving the motor.

Abstract: Disclosed herein is a stator assembly for a motor. The stator assembly comprises a stator core having a plurality of teeth around each of which a stator coil is wound, a first insulator coupled to one side of the stator core to provide insulation between one tooth and an adjacent tooth, a second insulator coupled to the other side of the stator core to provide insulation between one tooth and an adjacent tooth, and a three-phase terminal inserted between the stator core and the second insulator and protruded partially to the outside of the second insulator to be electrically connected to an inverter. According to the present invention, there are advantageous effects that since the three-phase terminal is assembled between insulators, breakaway and breakage of the three-phase terminal can be prevented and that insulation effect and assembly capability thereof are enhanced.

Abstract: The present invention relates to a motor driving control system and a control method thereof. The purpose of the present invention is to provide a motor driving control system and a control method thereof, which may change electric current limiting logic, which is applied to a BLDC motor for a cooling fan, in response to an operating speed of the motor to stably protect the motor from an overload in a low-speed driving state as well as an overload in a high-speed driving state.
