Abstract

The invention relates to electrical engineering. The aim of the invention is to simplify the design and increase the energy performance. The valve motor contains an electric machine with a multi-pole inductor and a crust winding connected to a power source via keys controlled by signals from a rotor position sensor (DPR) containing sensitive elements and a magnetically conducting screen. The signal element DPR is made in the form of arcuate sectors, mounted on the end of the inductor at its poles. The screen is made in the form of a figure mask with protrusions and is fixed on the same side of the end part of the inductor so that the protrusions are between the signal sectors. The invention can be used in an electric drive with high-torque valve motors. 1 hp f-ly, 2 ill. (L

Description

one

The invention relates to electrical engineering and can be used in a torque actuator with an electric motor (VD).

The purpose of the invention is to simplify the design and increase the energy performance of a multi-pole VD by increasing the accuracy of the output signal of the rotor position sensor (DPR).

FIG. 1 shows the ID, cross section; in fig. 2 shows section A-A in FIG. one.

The electric motor contains an electromechanical converter with a multipolar inductor with permanent magnet and rotor winding 2 located on the stator and connected to the source of purchase via keys controlled by signals of the rotor position sensor (power source and keys not shown) located on the rotor 1. Sensitive elements, made, for example, in the form of nascene chokes, consisting of winding 3 and permalloy core 4, are mounted in the case 5, which is the stator of the DPR and mounted on the stator 6 of the electric machine with adjustable angular position for adjusting the DPR.

The signal elements of the DPR are made in the form of a series of arcuate-shaped magnet bars of the 7 sectors, the angular size of which
