Abstract
PURPOSE:To simplify starting of a motor at the time of starting a pump at a low temperature by preheating said motor to a temperature, at which the motor does not burn, and by conducting the heat to said pump to weaken the viscosity of oil. CONSTITUTION:First, there are set two set values Pp corresponding to a temperature, at which a motor 1 does not burn, and Pm corresponding to a pump temperature, at which said motor 1 can be started. Before a pump 2 is started in a state where its temperature is higher than the set value Pp, a rated voltage is applied to the motor 1. On the other hand, when the pump is started in a state where the pump temperature is lower than the set value Pp, a rated voltage is first applied to the motor 1. When the temperature of said motor 1 reaches the set value Pm, a low voltage is applied to the motor 1 and the temperature of said motor 1 is conducted to the pump 2. When the temperature of said pump 2 reaches the set value Pp, the rated voltage is applied to the motor 1.
