A reconfigurable rotating electric machine having a rotor to rotate in association with a stator. Coils are arranged to form the windings of one or more phases. Each coil or group of coils has a pair of terminals to receive an electrical input. Switches are arranged to connect each coil or group of coils in series or parallel with another coil or group of coils to form defined coil topology configurations. A processor has memory storing settings to determine a state of each of the switches for each of the defined coil topology configurations. The switches are controllable to connect the coils into a force expansion topology configuration to form an electrical machine having two, four, or more virtual poles.

A compressor includes a casing accommodating a compression mechanism, a detection device having a detection face configured to detect an internal state of the casing, an elastic member, and a cover mounted to the casing to cover the detection device and a part of the elastic member. The detection face is located opposite an outer peripheral face of the casing. The elastic member includes a first portion overlapping the detection device and a second portion not overlapping the detection device, as seen in plan view. The cover is configured to press the second portion of the elastic member against the casing, with the first portion of the elastic member pressing the detection device against the casing.

A power tool which contains a casing, a brushless motor (22) mounted inside the casing, a user actuated switch (38) mounted on the casing, and a circuit board (32) mounted inside the casing. The brushless motor (22) is adapted to drive one or more movable parts in the power tool. The circuit board (32) is mechanically connected to the brushless motor (22) and the switch (38) at the same time. As only a single, integrated circuit board (32) is configured in the power tool, the manufacturing cost is reduced and greater reliance and electrical safety can be achieved.
