摘要： A magnetically-levitated blood pump with an optimization method that enables miniaturization and supercritical operation. The blood pump includes an optimized annular blood gap that increases blood flow and also provides a reduction in bearing stiffness among the permanent magnet bearings. Sensors are configured and placed optimally to provide space savings for the motor and magnet sections of the blood pump. Rotor mass is increased by providing permanent magnet placement deep within the rotor enabled by a draw rod configuration.

摘要： An energy-saving magnetic bearing device with no bias current for making the relation between the excitation current and the magnetic force of the electromagnet linear is provided. In a magnetic bearing device for supporting a rotor 1 serving as the magnetic piece in a levitating state allowing free rotation at a specified position by the magnetic force of a pair of electromagnets 2, 3, the electromagnets 2, 3 are constituted to interpose the rotor 1 and face each other. A driver 204 is a PWM (pulse width modulation) type driver for controlling the excitation current in the electromagnets 2, 3 by modulating the pulse width of a voltage driven at a specified carrier frequency fc, and includes a resonator means for electrically resonating at a frequency equal to the carrier frequency fc. When an excitation current flows in either one of the pair of opposing electromagnets 2, 3, then the other magnet is regulated so that the DC component in the electromagnet excitation current is zero, and a voltage is applied via the resonator means to the electromagnet whose DC component in the excitation current is discharged to zero.

摘要： A rotary motor and a rotary magnetic bearing are integrated in a compact assembly (10) that is contactless. A stator assembly (16) surrounds a ferromagnetic rotor (18) with an annular air gap (20) which can accommodate a cylindrical wall (12e), e.g. of a chamber (12), for semiconductor wafer (14) processing. The stator assembly (16) has a permanent magnet or magnets (38) sandwiched between vertically spaced magnetic stator plates (36) with plural pole segments (36a). The rotor (18) is preferably a ring of magnetic stainless steel with complementary pole teeth (18c). The stator assembly (16) levitates and passively centres the rotor (18) along a vertical axis and against tilt about the either horizontal axis (26,28), provides a radial position bias for the rotor (18), and establishes a motor flux field at a the rotor poles (18c). Polyphase coils (40) wound on the stator plates (36) produce a rotating flux field that drives the rotor (18) as a synchronous homopolar motor. A controller (54) energizes control coils (42) wound on each stator pole segment (36a) in response to a sensed physical position of the rotor (18) and can actively damp oscillations that may overcome the passive centering.
