Abstract
PURPOSE: To attain low noises and high efficiency by simple circuit constitution of low cost by a mechanism wherein a motor for a cooling fan and a contactor for driving a motor for power steering are connected to ensure that input to the motor for the cooling fan is fed from the contactor.
CONSTITUTION: In a control circuit for a motor for a cooling fan cooling a motor 3 for travelling of a battery type fork lift, the number of revolution of the motor 11 for the cooling fan is decreased or the motor 11 is stopped during the time when a car temporarily stops, and noises are lowered. The motor 11 for the cooling fan and a contactor 7 of a motor 8 for power steering are connected to ensure that input to the motor 11 is obtained from the contactor 7 while the input is also acquired from a key switch 9 through a resistor 13 so that the motor 11 for the cooling fan can fully be operated during the time when the car travels. The contactor 7 for short- circuiting the resistor is mounted at both ends of the resistor 13, and the contactor 7 functions by the making of a forward and reverse turn change-over switch 5.
