  • Phase converter for motor
    Patent number: 4777421
    Abstract: A single-phase to three-phase converter for starting and running a single, three-phase, load carrying induction motor having first, second and third Y-wound stator windings from a single phase power supply comprising a connector for connecting the input conductors to the converter to a source of single-phase alternating current, a connector for connecting the output conductors from the converter to the three-phase induction motor and adapted to connect one single-phase input conductor to the first stator winding and the other single-phase input conductor to the second stator winding, a bank of run capacitors connected between the first powered stator winding and the third unpowered stator winding to develop a voltage in the third winding at a phase angle different from the phase angles in the first and second powered windings, a potential-type relay comprising a set of normally closed contacts and a winding to open them, the windings connected between the second and third stator winding, a slave relay compris

  • Single phase to three phase dynamoelectric converter
    Patent number: 4656575
    Abstract: Single phase to three phase dynamoelectric converter for generating three-phase current from a single-phase input comprising a three-phase electric motor generator having first, second and third Y-wound stator windings, a bank of run capacitors connected between the first powered stator winding and the third unpowered stator winding, a normally closed potential-type relay with its winding connected between the second and third stator windings, a normally open slave relay with its winding connected between the first stator winding and the potential relay winding through the set of normally closed potential relay contacts, and a bank of starter capacitors connected between the third stator winding and one of the slave relay open contacts adapted to provide phase shifted starting power to the third stator winding when the single phase energy is applied and disconnect from the third stator winding to allow the converter to run and produce balanced three-phase power that can be drawn from all three stator windings
