Abstract
The utility model relates to a car motor with interference-resisting performance, which is composed of a casing (4), a end cover (1), a big gear (2), a worm (5), a commutator (6), an armature (7), a magnetic shoe (8), a carbon brush (11), two duplex gears (3), and a motor operating loop, wherein the worm (5) can be supported in rotation on the casing (4) by a bearing (9). The two duplex gears (3) are composed of coaxial small gears and worm wheels. The small gears and the big gear (2) are engaged. The worm wheels and the worm (5) are engaged. A filter circuit composed of two inductors (12) and four capacitors (13) are connected to the motor operating loop. The filter circuit and pulse frequency generated by the motor operating can carry out oscillation and resonance, so as to reach the filtering action of matching with the pulse frequency, electronic devices in a car, such as, a sounder, a radio, a VCD, etc. can not be influenced by the generated pulse frequency when the motor operates.
Description
Technical field
The utility model relates to a kind of electric motor of automobile, specifically, relates to a kind of electric motor of automobile with interference free performance.
Background technology
General automobile does not have anti-interference and protective device at present; its shortcoming is: the pulse frequency that takes place when machine operation is seriously disturbed the electronic equipment on the automobile; as sound equipment, VCD etc.; make other personnel in driver and the automobile can not normally use the electronic equipment of required usefulness and normally listen to broadcast receiver, VCD etc.; the sound that this disturbing pulse frequency is sent makes the people feel vexed; when particularly automobile runs into abnormal conditions; can burn motor as stall, phenomenon such as stuck, make it can't operate as normal.
Summary of the invention
The purpose of this utility model provides a kind of electric motor of automobile with interference free performance, makes the driver can normally use the interior electronic equipment of car, Source Music, sound equipment, VCD etc.
The technical scheme that realizes above-mentioned purpose is: a kind of electric motor of automobile with interference free performance, by casing, end cap, gear wheel, worm screw, commutator, armature, magnetic shoe, carbon brush, two duplicate gears and motor rotation loop are formed, worm screw can be rotated to support on the casing by bearing, two duplicate gears are made up of coaxial pinion and worm gear, pinion and gear wheel engagement, worm gear and worm engaging, connected one in the motor rotation loop by two inductance and four filter circuits that electric capacity is formed, an inductance is connected between fast shelves binding post and the brush, the another inductance is connected between slow shelves binding post and the brush, and electric capacity is connected between fast shelves binding post and the ground connection, between fast shelves and the slow shelves binding post, between slow shelves binding post and the ground connection and between two brushes that are connected with inductance.
After adopting technique scheme, owing to connected one by two inductance and four filter circuits that electric capacity is formed in the motor rotation loop, an inductance is connected between fast shelves binding post and the brush, the another inductance is connected between slow shelves binding post and the brush, electric capacity is connected between fast shelves binding post and the ground connection, between fast shelves and the slow shelves binding post, between slow shelves binding post and the ground connection and between two brushes that are connected with inductance, thereby the pulse frequency that produces during motor rotation with can form a vibration resonant tank with this filter circuit, reach the filter action of this pulse frequency of coupling, make motor possess jamproof function, guarantee electronic equipment such as sound equipment in the automobile, broadcast receiver, the influence of the pulse frequency that VCD etc. are produced when not being subjected to motor rotation.
