Abstract:
1. A motor for a compressor comprising: a stator provided with a plurality of tooth portions formed long in a radial direction, and a plurality of slot portions recessed between neighboring tooth portions; coils wound on the tooth portions and the slot portions of the stator, and wound to form end coils at both upper and lower sides thereof in an axial direction, at least some of the coils being formed of aluminum; a rotor inserted in the stator with a certain gap and having conductors rotated by an electromagnetic induction of the coils; and a rotational shaft press-fitted in the center of the rotor for transferring a rotational force to a compression unit, wherein a height H of the end coil of the coil is formed in inverse proportion to an inner diameter D of the stator, an entire area TS of the slot portions is in proportion to the inner diameter D of the stator, and a width D of the tooth portion is in inverse proportion to the inner diameter D of the stator.
