摘要： In a drive system including a battery, a power generation device (PGD) including a generator mounted to an engine shaft, and a drive device (DD) including a motor for driving a driven component, a drive controller performs a drive control for PGD and DD and a switching control for a switching device. During a parallel connection, respective high-voltage side terminals (HVTs) of PGD and the battery are connected to a HVT of DD, and respective low-voltage side terminals (LVTs) of PGD and the battery are connected to LVT of DD. During a series connection, HVT of any one of PGD and the battery is connected to HVT of DD, and LVT of another one of PGD and the battery is connected to LVT of DD, and terminals of PGD and the battery, which are not connected to DD, are connected to each other.

摘要： A heat pump apparatus, including: a two-cylinder compressor including: an electric motor; two compression units to be driven by the electric motor, the two-cylinder compressor being structured to switch between two operation modes including single operation in which one of the compression units is brought into a non-compression state, and parallel operation in which both the compression units are brought into a compression state; an inverter drive control device supplying drive power to the electric motor of the two-cylinder compressor; an operation mode detecting-determining unit determining a current operation mode based on an electric signal acquired from the inverter drive control device; and a capacity control device determining a rotating frequency of the electric motor so that a temperature of a target object is brought close to a set value, to thereby control the inverter drive control device based on a result of determination of the operation mode detecting-determining unit.

摘要： Provided is a rotating electric machine. Angles formed by tooth center axes of adjacent teeth are defined as tooth pitch angles. Maximum tooth pitch angles are defined as first tooth pitch angles α1. At least one of tooth pitch angles become smaller as proceeding from the first tooth pitch angles α1 in a clockwise direction and a counterclockwise direction, respectively, and such tooth pitch angles are defined as second tooth pitch angles α3. Cross-sectional areas of second coils, which are arranged in slots each formed between adjacent teeth corresponding to the second tooth pitch angles α3 in a cross-section perpendicular to a rotation axis, is smaller than cross-sectional areas of first coils, which are arranged in slots each formed between adjacent teeth corresponding to the first tooth pitch angles α1 in the cross-section perpendicular to the rotation axis.

摘要： Given a first intersection point of the surface of a rotor and a straight line that joins a central point of a permanent magnet on a stator side and a tooth tip section closest to the central point of the permanent magnet on the stator side, a flange is formed outward of an arc having, as the radius thereof, a distance from a second intersection point of the inner peripheral face of the stator and a straight line that joins the rotation axis of the rotor and the first intersection point, up to the tooth tip section.
