A winding method for a BLDC motor is disclosed. The winding method is configured to successively wind two magnetic wires across each core slot and its adjacent core slot (over two pitches) in a brushless direct current (BLDC) motor including a U-phase winding, a V-phase winding, a W-phase winding and a GND winding, 12 core slots, and a ground terminal. The winding method includes: a first step of moving and winding the magnetic wires; a second step of moving and winding the magnetic wires; a third step of moving and winding the magnetic wires; a fourth step of moving, winding, moving, and cutting the magnetic wires; a fifth step of moving and winding the magnetic wires; and a sixth step of moving the magnetic wires, passing the magnetic wires through an adjacent core slot and the ground terminal, and moving and cutting the magnetic wires.

Winding method for BLDC motor

An electromagnetic compatibility (EMC) terminal ground for a brushless direct current (BLDC) motor is disclosed. The EMC terminal ground includes a metal ground configured to be applied to the BLDC motor, the BLDC motor including: a stator block configured to include a base portion and a ball bearing reception portion; a rotor configured to be coupled to the stator block; a stator core located inside the rotor; a shaft configured to pass through the rotor and the stator core; a heat sink installed at the lower end of the stator block; and a PCB cover configured to cover the lower end portion of the heat sink; and a pair of ball bearings disposed at intervals; wherein the metal ground grounds the stator core, the rotor, and the heat sink.

EMC terminal ground structure for BLDC motor

A motor equipped with dampers for reducing the vibration and noise of a rotator is disclosed. The motor includes: a stator block configured such that a core around is fastened and installed in the upper outer portion of the inside of a cover; a printed circuit board (PCB) fastened and installed below the stator block inside a motor housing; a shaft installed inside the stator block; and a rotor configured to include a magnet; wherein the motor housing includes an upper cover and a lower cover, a plurality of fastening portions is formed on the upper cover, and a plurality of fastening depressions is formed on the lower cover; and wherein the motor further includes dampers configured to receive and accommodate the fastening portions, to be inserted over side surfaces of the base portion of the stator block, and to cancel vibration and noise.
