Abstract
The utility model relates to a brushless direct current motor, in particular to a double-speed direct-current motor special for an electric automobile, which mainly aims at solving the problems as follows: for the existing motor used in the electric automobile, the output needs an inverter, which leads the speed change and installation of the electric automobile to be inconvenient and noise to become high, and the extended driving range of the electric automobile can not be increased. The double-speed direct-current motor special comprises a motor shell, a stator, a rotor, magnetic steel and an end cover, wherein stator coils adopt two groups of double-layer homopolar coils, and nine taps of the stator coils are output through a junction box. The nine taps of the stator coils lead the two groups of coils to be connected in series or in parallel through external wires, thus increasing the motor power, realizing double-speed direct drive, having big torsion, high efficiency, low noise and energy conservation; and a speed adjusting device is matched for use, thus being capable of leading the extended driving range of the electric automobile by one-time charge to be up to over 500-600 kilometers.
