The control circuit is designed so that it is provided with a driver IC, which as a Hall signal input terminal, a temperature control input terminal, two voltage input terminals and two current output terminals which are connected with the two coils (L1,L2), to control the operation of the coils. The control circuit (10) includes a Hall element (12) which is connected with the Hall signal input terminal, in order to detect phase alterations in the two coils and then to transmit a signal. Also included is a heat sensor (13) which is connected with the temperature control input terminal. A rectifier (14) supplies a DC voltage to the voltage input terminals of the Hall element and to the two coils (L1,L2). The DC current is made available for the driver IC, the Hall element and for the two coils in order to operate them normally. The Driver IC in addition is provided with a frequency generator output terminal for determining the rpm of the motor. |
