Latest Patents

Hioki's latest patents include a driver circuit and method that effectively controls the amount of motor drive current to an appropriate value. This invention utilizes two coils to rotate a rotor by supplying currents with different phases to each coil. During a phase when one coil is in a high-impedance state, the induced voltage generated in that coil is detected. Based on the state of this induced voltage, an output control circuit adjusts the motor drive currents supplied to both coils. Another notable patent involves a stepping motor that also includes two coils. In this design, one terminal of one coil is grounded while the other terminal is set to a high impedance state. The induced voltage generated at that coil is detected relative to ground, allowing for controlled adjustments to the magnitude of the motor drive current supplied to the coils.
