摘要： An apparatus which estimates the temperatures of a motor without using a temperature sensor can achieve overheat protection by proper control. In an example, a heat generation amount calculation section calculates a heat generation amount of a motor. A current upper limit map has a current upper limit value corresponding to a temperature estimated value and a ratio map has a ratio corresponding to the temperature estimated value. A lower one of limited current values, determined using the two maps, controls energization of the motor. The heat generation amount calculation section includes a heat generation correction term, and a heat radiation correction term for calculating a function of the difference between the integrated value of the heat generation amount and a motor ambient temperature. If the ambient temperature becomes equal to or higher than a comparison temperature, then the heat generation amount is calculated without the heat radiation correction present.

摘要： A drum brake for braking a wheel disposed on the inside in the radial direction of an electric motor. The drum of the drum brake and an electric motor are disposed separate from each other, and thus wear powders of a brake shoe do not adhere to a permanent magnet of the electric motor. As a result, the wear powders do not adversely influence the performance of the electric motor, and the performance of the electric motor is maintained. The electric motor and the drum brake are disposed concentrically, so that the width of the wheel is reduced. Thus, a small and compact wheel is realized.
