Abstract: The foot machine according to the invention for a bass drum of a drum kit basically comprises a shaft mounted rotatably in a frame, a beater supported on the shaft, and a pedal connected to the beater, operation of the pedal bringing about an excursion of the beater. Also provided are permanent magnet restoring means which bring the displaced beater back into a resting position and which are formed by at least one inner and at least one outer permanent magnet arrangement arranged concentrically around the shaft.

Abstract: The invention relates to a solenoid valve having a coil, a magnet core, an armature, a yoke tube, a pole piece and a valve housing. The sealing and connection between the pole piece and the coil and/or the pole piece and the valve housing is effected by means of respective clamp-cutting edge connections each having a nose-like projection.

Abstract: A brushless, linear motor is provided in which the armature coils are cast in a resin to form an armature plate. A heat sink is attached along one edge of the plate with conductive pins (e.g. aluminum pins) extending through the plate and into the heat sink. Fans, attached to the heat sink, draw air across it in order to remove heat by convection. A wireless communications link transmits commutation data and/or armature position data to a motor controller.

Abstract: A motor, encoder/resolver, and/or dynamic brake assembly in which the dynamic brake, when part of the assembly, is mounted on a rear cover plate of a modular housing for the auxiliary components. When a resolver or encoder is part of the assembly, the motor shaft extends only a short distance beyond the resolver/encoder housing module; far enough to be engaged by the armature of the dynamic brake if the brake is part of the assembly. In an assembly that does not use a dynamic brake, the same rear cover plate is used to close the encoder/resolver housing module.
