Abstract
The utility model discloses a permanent-magnetic brushless DC change speed motor of an electric vehicle, which consists of a permanent-magnetic brushless DC motor and a speed changer, wherein the permanent-magnetic brushless DC motor is coupled with the speed changer to be directly connected into a whole, and an output shaft of the speed changer and a main shaft of a motor are on the same axis. The permanent-magnetic brushless DC change speed motor has the characteristics of having reasonable structure, saving space, and improving torque and drive capability greatly under the conditions of climbing and overloading due to the two-stage speed change of the speed changer, and the like.
Description
Affiliated technical field
The utility model relates to a kind of motor, especially is applicable to the DC permanent-magnetic brushless variable speed electric motors, particularly on the electric automobile.
Background technology
The power of present known electric automobile and transmission mechanism comprise motor, clutch, gearbox, power transmission shaft etc., the employed motor overwhelming majority is a permanent-magnet brushless DC electric machine, the electric automobile of this power drive mechanism, power drive mechanism disperses huge, function consumption is big, be difficult to guarantee under automobile climbing or the heavily loaded situation specific (special) requirements to torque and driveability, and volume is big, it is big to take up room.
Summary of the invention
Provide in order to overcome weak point of the prior art a kind of rational in infrastructure, make that automobile power assembly dwindles, the torque under save space, the climbing of raising automobile and the heavily loaded situation and the electric automobile DC permanent-magnetic brushless variable speed electric motors, particularly of driving force.
The technical scheme that its technical problem that solves the utility model adopts is: it comprises permanent-magnet brushless DC electric machine and variable-speed motor two large divisions, and permanent-magnet brushless DC electric machine and variable-speed motor coupling directly link into an integrated entity; Variable-speed motor is the two-stage speed change, makes the output shaft of variable-speed motor and electric machine main shaft on same axis by the two-stage speed change, constitutes coaxial transmission.
The beneficial effects of the utility model are: use on automobile, original motor, clutch, gearbox have been substituted, directly be connected with power transmission shaft, make the power drive system of automobile simpler, power consumption is few, power output is big, by the two-stage speed change of speed changer, make this DC permanent-magnetic brushless variable speed electric motors, particularly under the situation of automobile climbing and heavy duty, improve torque and driving force; And volume is little, saves the space.
