Abstract
A disk-shaped and coreless type electric motor for controlling the tilt of a throttle valve. The motor includes a field magnet having at least one pair of N and S poles and a stator armature having at least one set of coils disposed in face-to-face confronting relation to the magnet. The shaft of the motor is coupled directly to the shaft carrying the throttle valve, the latter shaft being urged by a spring toward a position where the valve throttles off the passage of air. The coil is so positioned relatively to the N and S poles of the magnet that when the coil is excited, any conductor portions thereof can act effectively to develop torque to rotate the magnet.
