  • Method and system for constant temperature control of motorized spindles
    Patent number: 11817807
    Abstract: The present invention provides a method and system for controlling the temperature of an electric motor by adjusting the electric losses in the motor. In an embodiment, the required load on the motor is determined and a first motor voltage is provided to meet the required load. A predetermined temperature set point for the motor is compared against the temperature of the motor and based on the temperature of the motor and the predetermined temperature set point, a secondary motor voltage is determined. The motor voltage may then be adjusted based on the calculated voltage and the motor load measurement adjusted based on the measured motor speed and actual motor voltage.

  • Pulse and gap control for electrical discharge machining equipment
    Patent number: 10259062
    Abstract: A method of detecting the state of a gap between an electrode and a workpiece in electrical discharge machining (EDM) equipment, the method including the steps of: prior to generating an electrical discharge to remove material from the workpiece, applying a low energy checking pulse across the gap during a checking phase period (Tc); and inferring a short circuit gap state when the gap current exceeds a current threshold (IT).
