摘要： A three-phase induction motor includes: a stator having a stator slot having an open slot structure for inserting a formed coil; and a rotor having a rotor slot into which a conductor bar is inserted, the rotor being placed on an inner side of the stator with a clearance between the rotor and the stator. The conductor bar has a polygonal cross-sectional shape having six or more angles, and both end portions of an outer-circumference-side edge surface of the conductor bar are rounded.

摘要： A rotor for an induction motor includes a first shorting end ring, a second shorting end ring, and a plurality of conductor bars. Each conductor bar has a first end and a second end and is coated with an electrically conductive material. The first end of each conductor bar is in electrical and mechanical contact with the first shorting end ring, and the second end of each conductor bar is in electrical and mechanical contact with the second shorting end ring. The conductive material is disposed between each conductor bar and the respective shorting end rings.

摘要： A rotor for an asynchronous machine has a laminated core and a short-circuit cage at least partially integrated in the laminated core. The short-circuit cage is designed with rods having or consisting of a first electrically conductive material and short-circuit rings having or consisting of a second electrically conductive material. At least one of the short-circuit rings is designed with a support ring, and each support ring is designed as a structure interlockingly and/or integrally cast onto or into the associated short-circuit ring.

摘要： There is a growing need for line-start single-phase electric motors that provide in combination high starting torque, high efficiency and low acoustic signature, particularly for use in hermetically sealed devices including, but not limited to, reciprocating piston systems for power generation and gas compression. This disclosure provides is a single-phase induction machine that meets this need.

摘要： A transverse flux induction motor (“TFIM”) is described in accordance with the present invention. The TFIM may be a linear induction motor or a rotary induction motor. The TFIM includes a primary motor element and secondary motor element. The primary motor element includes a plurality of coils and at least one magnetic element. The plurality of coils are arranged to generate a control flux along a first direction when power is applied to at least one coil of the plurality of coils and the at least one magnetic element is arranged to generate a bias flux in a second direction that is substantially transverse to the first direction. The secondary motor element is moveable in the first direction, relative to the primary motor element, in response to the control flux.

摘要： The invention relates to an asynchronous machine (1) as can be used particularly in electric vehicles or hybrid vehicles. The asynchronous machine (1) has a rotor (5) and a stator (3). The asynchronous machine is designed and controlled in such a manner that it has a pole pair number p of p=3. Because of the reduced yoke saturation that can consequently be achieved, the stator yoke (9) can be designed with a lesser height hy1, such that a ratio of the outer rotor diameter D2a to the outer stator diameter D1a can assume values between 0.7 and 0.8. As a result, enlarged rotor teeth (19) and correspondingly enlarged rotor grooves (21) can be formed in the rotor (5), such that electrical losses in the material in the rotor grooves (21) acting as the rotor coil element (23) are smaller in comparison to conventional asynchronous machines. The electrical losses occurring to a greater extent in the stator (3) compensating for this lead to a lesser warming of the stator (3) than would be the case with the rotor (5) as the stator (3) can be cooled by simple means. Overall, a higher continuous torque can thus be achieved with the asynchronous machine (1) according to the invention.

摘要： To reduce the number of mounted components in the power conversion device and drive device.Each high-side transistor and low-side transistor has an EGE-type structure of (emitter-gate-emitter type). A high-side driver includes a first pull-up transistor configured to apply a first positive voltage to a gate based on an emitter of the high-side transistor, and a first pull-down transistor configured to couple the gate to the emitter. A low-side driver includes a second pull-up transistor configured to apply a second positive voltage to the gate based on an emitter of the low-side transistor, and a second pull-down transistor configured to couple the gate to the emitter.

摘要： An electrically driven eccentric weight industrial vibrator comprises a housing, a stator, a rotor, and at least one eccentric weight. The housing defines an internal chamber. The stator is positioned within the internal chamber of the housing and is fixed in rotation relative to the housing. The rotor encircles the stator and is rotationally connected to the stator and the housing in a manner such that the rotor is able to revolve around the stator within the internal chamber of the housing. The eccentric weight is mounted to the rotor in a manner such that the eccentric weight is able to revolve about the stator together with the rotor.
