Motor with a heat dissipating assembly
First Claim
1. A motor with a heat dissipating assembly, comprising:
- a hollow block including an opening longitudinally and centrally defined in the hollow block, and multiple fins extending radially out from an outer periphery of the hollow block;
a stator mounted in the opening in the hollow block and forming multiple first gaps between a periphery of the opening in the hollow block and an outer periphery of the stator, a through hole centrally and longitudinally defined in the stator and a series of slots defined in a periphery of the through hole in the stator, each slot receiving a coil in the stator;
a rotor rotatably mounted in the through hole in the stator and a second gap formed between the coil and the rotor, the rotor including a body and a shaft co-axially extending through the body, multiple ventilating holes longitudinally defined in and extending through the body around the shaft, a series of blades extending down from a bottom of the body around the shaft;
a block end cap attached to the hollow block, the block end cap including multiple bores defined in and extending through the block end cap, multiple recesses defined in an edge of the block end cap and corresponding to the fins of the hollow block;
a cover attached to the block end cap to form a space between the block end cap and the cover, wherein the bores in the block end cap communicate with the space between the block end cap and the cover, a tube extending through the cover and secured on the cover so that air can flow in the space between the block end cap and the cover;
a base member attached to a bottom of the hollow block, the base member including a cavity defined to correspond to and communicate with the opening in the hollow block, a first path laterally defined in and extending through the base member to communicate with the cavity in the base member;
a stator separator mounted in the cavity in the base member and abutting a bottom of the stator, the stator separator including a groove defined to movably receive the blades of the rotor and a passage laterally defined in and extending through the stator separator to communicate with the groove in the stator separator, the passage aligning with and communicating with the first path in the base member;
a casing attached to the base member and the hollow block, the casing containing a space to mount the motor and having a fairing attached to an outer periphery of the casing, the fairing having a through hole defined to communicate with the first path in the chamber and the tube in the cover extending into the casing; and
a cooling fan mounted on a top of the casing to close the casing and blow air into the casing.

Abstract
A motor with a heat dissipating assembly includes a hollow block, a stator fixedly mounted in the block and a rotor rotatably mounted in the stator. A first gap is formed between the block and the stator. A second gap is formed between the stator and the rotor. Multiple through holes are longitudinally defined in the rotor. A stator separator is mounted under the rotor. A groove is defined in the stator separator and communicates with a casing. An air current formed by the rotating rotor flows into the casing through the stator, rotor and the stator separator to form a closed circuit in the motor for dissipating heat. A casing is mounted around the motor and a cooling fan is mounted on the top of the casing to generate an air current to dissipate heat from the outer periphery of the motor.
