Small motor with double air ducts for cooling and resisting magnetic field

Abstract

The invention discloses a small motor with double air ducts for cooling and resisting a magnetic field. Aluminum alloy air duct, the top of an inner cavity of the aluminum alloy air duct is rotationally connected with aluminum alloy high-speed fan blades. A motor shaft center is rotatably connected to an inner cavity of the aluminum alloy air duct, a first high-speed ball bearing is movably connected to the top end of the motor shaft center and located below the aluminum alloy high-speed fan blades, and the top end of the motor shaft center is rotatably connected with the inner surface of thefirst high-speed ball bearing. The invention discloses a small motor with double air ducts for cooling and resisting a magnetic field. The aluminum alloy high-speed fan blades and the aluminum alloy air duct are arranged; the aluminum alloy high-speed fan blades rotate to suck outside air into the aluminum alloy air ducts for cooling through negative pressure siphoning, the double air ducts are matched with negative pressure siphoning of the aluminum alloy high-speed fan blades, so that the temperature rising speed of the motor is greatly reduced when the inner cavity of the small motor works,and the small motor works more stably through the arrangement of the shell shielding magnetic sleeve and the shockproof silica gel sleeve.

Description

Technical field [0001] The invention relates to the technical field of motors, in particular to a small motor with dual air ducts for cooling and diamagnetic field. Background technique [0002] The motor is the electric motor and the engine. The working principle is that the starter rotor is driven to rotate by the energized coil in the magnetic field, and the pinion on the rotor drives the engine flywheel to rotate. The electronic starter is the motor that people usually refer to now, also known as the starter. It drives the starter rotor to rotate through the energized coil in the magnetic field, and the pinion on the rotor drives the engine flywheel to rotate, thereby driving the crankshaft to rotate and drive the car. The initial low-speed high-torque hydraulic motor was developed from a stator and rotor part of the oil pump Then, this part is composed of an inner gear ring and a matching gear or rotor. There are many types of motors. According to their power supply methods...
