DIRECT CURRENT REGENERATIVE ELECTRIC MOTOR AND ROTATION DIRECTION SWITCHING APPARATUS

WIPO Patent Application WO/2012/026170

A1

[Problem] To provide a direct current regenerative electric motor that carries out regenerative braking immediately after an electricity supply is interrupted only upon an operation of an electricity supply operation unit, and is capable of accumulating electricity obtained through said regenerative braking, as well as a rotation direction switching apparatus that switches the direction of rotation of the direct current regenerative electric motor. [Solution] A direct current regenerative electric motor comprises: an electricity supply signal generator unit, which outputs an electricity supply signal in response to a first instruction signal; a regeneration signal generator unit, which outputs a regeneration signal in response to a second instruction signal; a segment, further comprising a detector unit which detects a magnetic pole of a rotor and applies a polarity to the electricity supply signal, and a switching unit that changes the direction of load current, intermittently allowing same to flow; and a regenerated electricity control unit, which multiplies and accumulates induced electricity. The direct current regenerative electric motor either drives rotation or regeneratively brakes, in response to the instruction signals. The direct current further comprises a rotation direction switching apparatus, which switches the direction of rotation by selecting a magnetic coil group and supplying an electricity supply signal, allowing an electric-powered automobile to move forward or in reverse.
