  • Publication number: 20230011435
    Abstract: A method for controlling a brushless and sensorless, direct current electric motor (3) for motor vehicle equipment, wherein the electric motor (3) comprises a rotor and phases (A, B, C) powered by a pulse width modulation applied to a power inverter (1) of the electric motor (3), and wherein, beyond a minimum threshold (Smin) of the rotation speed of the rotor, the position of the rotor is determined from a measurement of electromotive forces at the phases (A, B, C) of the electric motor (3), said control method is characterised in that, in the event of a command (104) to stop the electric motor (3), the speed of rotation of the rotor is reduced (105) from a nominal speed to a predetermined rotation speed (V1) within a range between the minimum threshold (Smin) and 10% above said minimum threshold (Smin) by modifying the pulse width modulation, then the electric motor (3) is stopped (106) in a predetermined position by short-circuiting the branches (A, B, C) of the inverter (1) when the predetermined position

  • Publication number: 20220348166
    Abstract: The invention relates to a geared motor comprising a first brushless electric motor part having a stator, a rotor and a drive shaft, a second part having an output shaft and a reduction gear mechanism and an electronic part. The reduction gear mechanism comprises an output shaft, a worm and a toothed wheel designed to be engaged by the worm and to drive the output shaft in rotation. The geared motor comprises at least one rolling guide bearing disposed on the drive shaft and a multipolar magnet for measuring the position of the rotor. The rolling bearing is disposed between the measurement magnet and the worm such that the electric motor can be controlled depending on the measurement of the position of the rotor.

  • Publication number: 20220194324
    Abstract: The present disclosure provides a pattern projecting lamp and a motor vehicle—in particular, a motor vehicle comprising a pattern projecting lamp. The pattern projecting lamp comprises an optical module configured to provide a projection light beam having a pattern, a support comprising a base and a rotary arm connected rotatably to the base, wherein the optical module is disposed in the rotary arm, and the rotary arm is provided with a light exit for the projection light beam to be emitted through. The pattern projecting lamp can project a light beam having a predetermined pattern at a suitable angle, as tailored to display additional information or provide auxiliary illumination on the vehicle body of the motor vehicle or at a peripheral region of the motor vehicle.
