Abstract

A DIRECT CURRENT MOTOR (12), ACTUATED BY AN ELECTRIC POWER OF A BATTERY (22), IN WHICH A TAP TERMINAL (TT) IS ARRANGED AT AN INTERMEDIATE POSITION OF EACH OF THREE COILS (14), IS CONTROLLED BY A MOTOR CONTROL APPARATUS (11). WHEN THE OPERATION OF THE MOTOR (12) IS STARTED, A LOW ROTATIONAL SPEED IN THE MOTOR (12) IS DETECTED, AND AN ENTIRE COIL (14) ACTUATING OPERATION IN WHICH A MOTOR CURRENT PASSES THROUGH EACH ENTIRE COIL (14) IS SELECTED AND PERFORMED. THEREFORE, THE MOTOR (12) IS ACTUATED BY A HIGH TORQUE. WHEN THE ROTATIONAL SPEED IS HEIGHTENED, A HIGH ROTATIONAL SPEED IN THE MOTOR IS DETECTED, AND A PARTIAL COIL ACTUATING OPERATION IN WHICH A MOTOR CURRENT PASSES THROUGH EACH PARTIAL COIL BETWEEN THE TAP TERMINAL (TT) AND ONE END OF THE COIL (14) IS SELECTED AND PERFORMED. THEREFORE, THE MOTOR (12) IS ACTUATED BY A LOW TORQUE. WHEN A VOLTAGE OF THE BATTERY (22) DECREASES BECAUSE THE BATTERY (22) IS ALMOST USED UP, THE ROTATIONAL SPEED IS LOWERED, A LOW ROTATIONAL SPEED IN THE MOTOR IS DETECTED, AND THE ENTIRE COIL (14) ACTUATING OPERATION IS AGAIN PERFORMED. THEREAFTER, EVEN THOUGH THE VOLTAGE OF THE BATTERY (22) MOMENTARILY INCREASES, THE PARTIAL COIL ACTUATING OPERATION IS FORBIDDEN BY A SELECTION FORBIDDING UNIT (20). THEREFORE, THE MOTOR (12) CAN BE STABLY OPERATED WITHOUT REPEATING ANY OPERATION SWITCH (13). (FIG 3)
