Abstract
The utility model relates to a motor, in particular to a brushless high-speed toothed motor for electric bicycle. The brushless high-speed toothed motor for an electric bicycle comprises a stator, a rotor, a sensor, a left end cover, a right end cover, a left inner cap, a right inner cap, an outer gear ring, a planet wheel, a sun gear, a left half axle, a right half axle, a duplex bearing and a clutch. The rotor is connected with the sun gear, the planet wheel is arranged on the right inner cap, the sensor is arranged on the reverse surface of the left inner cap, the clutch and the outer gear ring are connected in the left end cover, and the right and left half axles are respectively arranged on the right and left inner caps. Since the sensor is arranged on the reverse surface of the left inner cap, the brushless high-speed toothed motor for the electric bicycle of the utility model avoids the damage to elements as a result of the high-temperature of the motor. The efficiency curve at the low power end value does not decrease, and the efficiency curve at the high power end increases obviously. The dynamic characteristic of the motor is obviously improved, the character is hard, and a special controller is provided. The brushless high-speed toothed motor for the electric bicycle has the advantages of open-phase protection, over-current protection, reliability, continuous and stable speed regulation and no oscillation.
Description
Affiliated technical field
The utility model relates to a kind of motor, and especially electric bicycle has the tooth motor with brushless high speed.
Background technology
Electric bicycle has entered in the daily life as a kind of walking-replacing tool, progressively replaces bicycle.The motor that electric bicycle is in the market used has been generally and has been brushed with the tooth motor, had brush slowspeed machine, brushless slowspeed machine, and the controller of brush motor difficulty is done,
Summary of the invention
In order to overcome the deficiency of existing electric bicycle with motor, the utility model provides a kind of electric bicycle with brushless high speed the tooth motor to be arranged.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of electric bicycle has the tooth motor with brushless high speed, have stator, rotor, transducer, left end cap, right end cap, left inner cap, right inner cap, external toothing, planetary gear, central gear, left half axle, right axle shaft, duplex bearing, clutch, rotor and central gear are linked and packed, planetary gear is installed in the right side and covers, transducer is installed in left inner cap reverse side, clutch, external toothing are connected in the left end cap, cover in about left and right sides semiaxis is installed in respectively.
Further: described stator is provided with wire casing, and the number of wire casing is 21 grooves.
The beneficial effects of the utility model are that transducer is installed in left inner cap reverse side, has avoided the damage of electromotor high-temperature to element; efficiency curve does not reduce at the low-power end value; the high power end is significantly improved, and the dynamic characteristic of motor is obviously improved, and characteristic is hard; is furnished with nonshared control unit; open-phase protection, overcurrent protection, reliable, speed governing is continuous; steadily, friction.
