    Abstract: A rotary solenoid (1) includes a stator (10), a rotor (40), and a torsion spring (50) connected between the stator (10) and the rotor (40). The stator (10) includes an armature (13) having three stator poles (14, 15) cooperatively defining a substantially cylindrical space (18) and a coil (19) wound about one of the stator poles (14). The rotor (40) includes a shaft (42) rotatably assembled to the stator (10) and a rotor core (44) fixed to the shaft (42) and received in the cylindrical space (18). The rotor core (44) has three rotor poles (43) corresponding to the stator poles (14, 15). The rotor (40) stays at a first position under the force of the torsion spring (50) and rotates to a second position under the force of the torsion spring (50) and the magnetic force of stator (10) when the coil (19) is powered.

    Abstract: An apparatus includes multiple brushes (30, 30B, 30A, 30a, 30b) and a commutator (10) that has multiple commutator plates (12, 12A, 12B, 13B) to contact the multiple brushes for commutation in order to convert electrical energy into mechanical energy or vice versa. A brush may include an EMI suppression mechanism (30, 38A, 38B) to reduce random electromagnetic interferences or a filter circuitry (400B) to reduce the overall level of electromagnetic interferences. An EMI suppression mechanism may include a specially designed brush that leverages dielectric properties or mechanical properties of the brush to reduce electromagnetic interferences. An EMI suppression filter circuitry may include an all-capacitor filter circuitry that does not include beads or chokes.
