Abstract
The present disclosure generally relates to a motor assembly. comprising an electrical motor and a control unit connected to and adapted to control an operation of the electrical motor. In line with the present disclosure. at least one multi-axis magnetic sensor is used for measuring a magnetic flux originating from the magnetic poles of an external rotor comprised with the electrical motor, where the measured magnetic flux is used for controlling a current provided to the electrical motor.

A motor assembly, comprising:
- an electrical motor, and
- a control unit connected to and adapted to control an operation of the electrical motor,
- wherein:
- the electrical motor comprises an internal stator and an external rotor,
- the external rotor is provided with a preset number of pole portions arranged at an inside of the external rotor and adapted to form magnetic poles,
- the motor assembly further comprises at least one single chip multi-axis magnetic sensor connected to the control unit and arranged in a proximity of a periphery of the external rotor to measure a magnetic flux originating from the magnetic poles of the external rotor, and
- the control unit is further adapted to:
- determine an angular position of the rotor based on the measured magnetic flux, and
- control a rotation of the electrical motor based on the determined angular position.
