Motor housing and motor

Abstract

A motor housing and a motor are provided. The motor housing comprises a housing (1); a spiral water channel (2), an air inlet hole (3) and a communication channel (4) are arranged on the housing (1).The spiral water channel (2) extends spirally along the axial direction of the housing (1), the air inlet hole (3) is arranged on the outer surface of the housing (1) and extends radially of the housing (1), and the communication channel (4) is arranged on the inner peripheral side of the spiral water channel (2) and communicates with the air inlet hole (3). According to the motor housing of the invention, the radial ventilation holes on the motor stator can be effectively ensured to be located on the same plane, the structure is simple, and the machining difficulty is low.

Description

technical field [0001] The invention belongs to the technical field of motors, and in particular relates to a motor casing and a motor. Background technique [0002] see figure 1 As shown, the existing high-speed motor cooling structure is composed of 4 parts, 1, casing; 2, spiral water channel; 3, radial ventilation holes; 4 inlet / outlet pipes; 5, air inlet, spiral water channel 2 It is used to cool the stator of the motor, and the radial ventilation holes 4 are used to cool the rotor of the motor; but because the spiral water channel 2 advances in a spiral, the air inlet holes in the circumferential direction of the casing 1 cannot be evenly distributed on the same plane, otherwise they will be pierced waterways leaking, such as figure 1 As shown, the three air inlets 5 are not on one plane among the figure. Since the air intake hole 5 on the casing 1 communicates radially with the radial ventilation hole 3 on the motor stator, if the air intake holes are not on the sam...

Problems solved by technology

[0003] However, for the motors of the prior art, the air inlet 5 on the casing 1 communicates radially with the radial ventilation holes 3 on the motor stator, so if it is necessary to ensure that the radial ventilation holes 3 on the motor stator are arranged on the same plane On the other hand, the air intake holes 5 on the casing 1 need to be arranged on the same plane, so the more radial ventilation holes 3, the more air intake holes 5 on the casing 1, the higher the machining accuracy, and satisfying The more difficult it is to set the position of the air intake hole 5, if the processing deviates, the wall thickness of the spiral water channel near the air intake hole 5 will become thinner and the safety factor will decrease, and even cause water leakage
