Latest Patents

One of Lequesne's latest patents is for a lubricant supported electric motor that includes a magnetic rotor centering mechanism. This innovative design features a stator with a stator raceway and a rotor that is rotatable relative to the stator. The rotor is designed with a gap between its rotor raceway and the stator raceway, where lubricant is utilized to support the rotor. The rotor also includes multiple poles arranged in a circumferentially spaced manner, while the stator has poles extending radially towards the rotor. This design allows for individually controllable stator coil windings that generate magnetic forces to center the rotor effectively.

Another significant patent by Lequesne is a system and method for estimating the speed of an induction motor using a soft starter system. This system includes a motor control device that connects the motor to a power source. The device comprises several switching devices, including at least one thyristor for each motor phase. The controller within the device is programmed to disconnect the power source for a predetermined time after a series of cycles of the mains phase voltage. During this time, it measures back-emf voltage to estimate the motor's operating characteristics before reconnecting the power source.
