  • Patent number: 12357713
    Abstract: Inductive heating systems and method of controlling the same to reduce biological carryover are disclosed herein. An example system includes an induction heater including a tank circuit, the tank circuit including a work coil and a sense coil. The sense coil is to detect a magnetic field generated by the work coil and to output signals in response to the detection. The example system includes a controller to cause the tank circuit to oscillate at a resonant frequency in response to the signals and a power drive unit in communication with the controller and the induction heater. The power drive unit is to adjust power provided to the induction heater in response to the controller driving the tank circuit to oscillate at the resonant frequency.

  • Publication number: 20250183771
    Abstract: Disclosed are a glue spreading block, device and method for bonding a motor core, and a glue dot thereof. The glue spreading device includes a glue spreading block for bonding the motor core, where a shape of the glue spreading block can be set based on actual needs, and the glue spreading block is configured to spread glue internally absorbed on a silicon steel sheet when the glue spreading block is in contact with the silicon steel sheet. The glue spreading block for bonding the motor core provided in the present disclosure can spread the glue on the silicon steel sheet by means of printing, which can not only ensure the consistency of a size of glue spots, but also have a long service life, and feature reduced maintenance frequency and simple maintenance, prolonged maintenance cycle and improved production efficiency.
