<p>A control apparatus and method for a brushless direct current hub motor are provided. The control apparatus for a brushless direct current hub motor includes an input unit generating a forward/reverse RPM control command of the motor, a sensor unit detecting rotation of the motor, a controller outputting a motor driving signal by combining a motor rotational signal of the sensor unit with the RPM control command of the input unit, a switching device unit supplying a driving current to the motor by performing switching operation in accordance with the combined signal, and a brushless direct current hub motor rotating by the driving current. The brushless direction current hub motor has a multi-phase independent parallel winding. The controller drives the switching device unit such that a switching-on time of a lower end signal of the H-bridge is longer than a switching-on time of an upper end signal of the H-bridge to eliminate residence power of a motor coil. An apparatus/method is provided. The residence current of the motor coil can be eliminated and thus hysteresis phenomenon can be prevented.</p> |
