摘要： The armature coils of a brushless linear motor are cast in 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.

摘要： A power control and commutation network for a brushless DC motor includes a first section proximate the motor and a second section remote from and connected to the first section by a pair of conductors. Included in the first section is a servo control amplifier defining a main motor power supply and, in the second section, a polyphase brushless DC motor, a commutation module, an auxiliary power supply for the module, motor rotor position sensors and a switching network, the motor stator coils being connected through the switching network to the conductors. The amplifier may have an amplitude modulated DC output and the output of a high frequency oscillator in the second section is AC coupled to the conductors and the auxiliary power supply with its input is AC coupled between the conductors. Alternatively, the amplifier is PWM and the auxiliary power supply includes a rectifier with an input connected across the conductors and a voltage regulator controlling the output voltage.

摘要： 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.

摘要： A two wire, brushless, d.c. motor power control system employs a rechargeable d.c. power source (e.g. a battery or a capacitor) to provide power to the commutation position sensing electronics, and commutation logic during dynamic braking and also if desired, during motor start-up after stopping or reversing direction. Current limiting is provided by sensing the two-wire motor current and using the communicating logic to modulate the turn-off/turn-on time of the communicating switches.

摘要： A vacuum chuck apparatus includes a vacuum chuck mounted on one end of a hollow shaft whose other end is connected through a rotary seal to a vacuum source. The seal includes a first member having a cap portion cemented to the shaft end and an axially bored frustoconical projection on its end wall and a second member having a frustoconical socket complementing the projection which partially nests in the socket. The second member has a radial pin loosely engaging a longitudinal slot in a stationary bracket to restrict its rotation and permit its axial movement. A spring loaded pressure plate bears on the outer end face of the seal second member.
