Problems solved by technology

[0003] The stepper motor has a simple structure and is widely used, and it is also widely used in the aerospace field. This environment requires particularly high stability of the stepper motor. The existing glue used for fixing the coil is not resistant to high temperature and low temperature. The disadvantage that it cannot be used in a vacuum. After using this glue for a period of time, the strength of the glue will decrease, or even be completely destroyed, and the coil will be short-circuited, which will cause the motor to fail to work.

Abstract

The invention relates to the field of motor impregnation, in particular to glue for high-temperature stepping motor coil fixation. The glue comprises a component A and a component B, wherein the component A is prepared from the following ingredients: ceramic, E-51 epoxy resin, maleimide, asbestos fiber and ethanol. The component B is prepared from the following ingredients: aromatic amine and molybdenum disulfide. The glue has excellent heat-resistant expansibility, is high temperature resistant and is less in internal friction, low in cracking possibility and high in insulativity.

Description

technical field [0001] The invention relates to the field of glue dipping for motors, in particular to glue for fixing coils of high-temperature stepping motors. Background technique [0002] The stepper motor is an open-loop control element stepper motor that converts electrical pulse signals into angular displacement or linear displacement. In the case of non-overload, the speed and stop position of the motor only depend on the frequency and number of pulses of the pulse signal, and are not affected by the load change. When the stepper driver receives a pulse signal, it will drive the stepper motor to press The set direction rotates a fixed angle, which is called "step angle", and its rotation runs step by step at a fixed angle. The angular displacement can be controlled by controlling the number of pulses, so as to achieve the purpose of accurate positioning; at the same time, the speed and acceleration of the motor rotation can be controlled by controlling the pulse fre...
