A synchronous motor having phase windings which are split or tapped and in which the conduction angle of the applied alternating current is varied at one or more taps to allow the motor to start in a controlled direction and be torque controlled to synchronous speed.

Control of synchronous electrical machines

The present invention provides a mixing valve () suitable for electric motor () actuation, particularly stepper motor actuation. It also provides a servo mixing valve system, which includes stepper motors for actuation and optionally includes a solenoid switched outlet manifold and a combination mixing and dye. The present invention also provides an actively controlled bathroom shower mixing system including temperature formation feedback.

Valve system for servo control of fluid flows

The fluid supply apparatus supplies and controls one or more fluids while adjusting/controlling one or more continuously parameters; and includes an outlet, at least one control valve and a touchless user control interface. For example a faucet has sensors mounted thereon to control water flow ( ) and temperature ( ). For example a user hand in field ( ) will increase temperature over time and decrease in field ( ). The on/off sensor field may include the water stream, a bi-colour light emitting diode indicates temperature, temperature feedback means maintains the desired temperature, a battery or super capacitor allows operation or fluid shut off if power fails, an anti-tamper feature requires the fluid to be shut off if more than one sensor is covered and a time prevents waster wastage. The hygienic touchless interface may be in a tile or flat plate. Other applications may include panel mounted fluid control systems for controlling a plurality of fluid types and associated parameters.
