Problems solved by technology

[0002] Most of the motors used for waveguide switch conversion on existing satellites are permanent magnet stepping motors, and the rotor is a ring-shaped permanent magnet with a single structure. The system needs to design the structure of the telemetry signal separately, which leads to complex structure and increased weight of the system.
At the same time, the stability of the magnetic properties and the accuracy of the centerline of the magnetic poles are extremely high, and it is difficult to magnetize the magnetic steel, resulting in low angular position accuracy.

Abstract

The invention discloses a micro hybrid stepping motor for a satellite. The motor comprises a motor rotor, a motor stator and a rotor bracket. The motor stator is connected to a stator winding, the motor rotor is installed on the rotor bracket and the motor rotor is provided with magnet steel, and the rotor bracket is provided with a telemetry cylinder for feeding a system position signal back. Thestepping motor of the invention has small volume and light weight, and the materials used in the motor can meet the requirements of normal use in an aerospace environment for a long time.

Description

technical field [0001] The invention belongs to the technical field of motors, and in particular relates to a miniature hybrid stepping motor for satellites. Background technique [0002] Most of the motors used for waveguide switch conversion on existing satellites are permanent magnet stepping motors, and the rotor is a ring-shaped permanent magnet with a single structure. The system needs to design the structure of the telemetry signal separately, which leads to complex structure and increased weight of the system. At the same time, the stability of the magnetic properties and the accuracy of the centerline of the magnetic poles are extremely high, and it is difficult to magnetize the magnetic steel, resulting in low accuracy of the angular position. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a miniature hybrid stepping motor for satellites, which can work on satellites and has a , light weight, high pre...
