Radiation-resistant and high-temperature-resistant stepping motor

Abstract

The invention belongs to the technical field of stepping motors, and particularly relates to a radiation-resistant and high-temperature-resistant stepping motor. In response to the problem that the existing stepping motor has a large amount of heat and is more likely to be interfered by external signals during use, the following scheme is proposed: the stepping motor comprises a motor body, the outer side of the motor body is hermetically and fixedly sleeved with a radiation-proof casing, a fixed box is arranged below the radiation-proof casing, one side of the motor body is fixedly connectedwith a first cooling fin, one side of the first cooling fin is fixedly connected with a plurality of heat conducting rods, the same second cooling fin is fixedly installed on one sides of the plurality of heat conducting rods, and a condensation pipe is arranged on the outer side of the second cooling fin in a winding mode. According to the invention, the structure is simple, the radiation resistance and the high temperature resistance of the stepping motor body are effectively improved, the manufacturing structure is simple, the production cost is low, the service life of the stepping motor body is effectively prolonged, and the stepping motor has a relatively strong and wide market popularization prospect.

Description

technical field [0001] The invention relates to the technical field of stepping motors, in particular to a radiation-resistant and high-temperature-resistant stepping motor. Background technique [0002] Stepper motor is an open-loop control motor that converts electrical pulse signals into angular displacement or linear displacement. It is the main executive element in modern digital program control systems and is widely used. 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 spee...
