Title: Henricus M Van Hout: Innovator in Motor Technology

Introduction

Henricus M Van Hout is a notable inventor based in Eindhoven, Netherlands. He has made significant contributions to the field of motor technology, holding a total of 6 patents. His work primarily focuses on devices that enhance the functionality and efficiency of brushless multi-phase d.c. motors.

Latest Patents

One of his latest patents is a device for the detection of an angle of rotation of a brushless multi-phase d.c. motor. This innovative device detects the angle of rotation of a rotor in relation to a stator, which is crucial for the effective operation of the motor. The rotor is equipped with a permanent magnet, while the stator contains multiple electrical windings. The device employs a drive circuit that applies pulse-shaped electric test signals to the windings when the rotor is stationary. A measurement circuit then detects flyback pulses generated by the motor in response to these test signals. The processing unit analyzes the durations of the detected flyback pulses to determine the angle of rotation, enabling the motor to start in a predetermined direction.

Another significant patent is a motor drive circuit with an emergency auxiliary power supply. This circuit is designed for driving an electromotor that features a permanent magnet rotor and one or more stator windings. In the event of a supply voltage failure, an emergency signal is generated, activating an auxiliary power supply circuit that extracts energy from the motor. This energy is then used to temporarily energize an auxiliary circuit, ensuring that critical functions, such as moving a magnetic head to an idle position in a hard disk drive, can still be performed.
