Abstract
The invention discloses a permanent magnet protective sleeve for a permanent magnetic motor. The permanent magnet ring of the permanent magnetic motor is coated with a heat insulation protective sleeve layer made of ceramic material. The permanent magnet protective sleeve is mainly used to a high temperature protective layer of the permanent magnet. Since the heat conduction coefficient of the ceramic heat insulation material is low, the permanent magnet can be prevented from being damaged by high temperature of a rotor, thereby prolonging the service lifetime of the motor indirectly.
Description
Technical field
The present invention relates to new-energy automobile manufacturing technology field, particularly relate to the permanent magnet sheath of a kind of magneto.
Background technology
Along with economic develops rapidly, automobile has become one of important trip mode of people, and electric automobile is because of its distinctive advantage that can reduce air pollution, it has also become the study hotspot of current automotive industry.Electric automobile, under the working conditions such as starting, climbing, needs bigger output torque, and now the travel speed of automobile is slow；In the occasion of some high-speed cruisings, then needing in a bigger scope can the travel speed of invariable power regulation automobile.
Summary of the invention
For solving the problems referred to above present in prior art and practical situation, the present invention provides the permanent magnet sheath of a kind of magneto.Coating one layer of heat-insulation protecting jacket outside the magnet ring of magneto, described protective jacket is made of ceramic materials.
Preferably, the thickness of described protective jacket is 0.8 ~ 1.5mm.
Beneficial effect:
The permanent magnet sheath of a kind of magneto that the present invention provides, is mainly used in the high hat resistant cover of permanent magnet, owing to the heat conductivity of ceramic insulating material is low, permanent magnet can be protected to exempt from the high temperature of rotor, indirectly improves the service life of motor.
Detailed description of the invention
Technical solution of the present invention is described in detail below.
Embodiments of the invention disclose the permanent magnet sheath of a kind of magneto, coat one layer of heat-insulation protecting jacket outside the magnet ring of magneto, and described protective jacket is made of ceramic materials.
Further, the thickness of described protective jacket is 0.8 ~ 1.5mm.Preferably, the thickness of protective jacket is 0.8mm, so can preferably with outer protective jacket with the use of.
The permanent magnet sheath of a kind of magneto that the present invention provides, is mainly used in the high hat resistant cover of permanent magnet, owing to the heat conductivity of ceramic insulating material is low, permanent magnet can be protected to exempt from the high temperature of rotor, indirectly improves the service life of motor.
Last it is noted that the foregoing is only the preferred embodiments of the present invention, it is not limited to the present invention, although the present invention being described in detail with reference to previous embodiment, for a person skilled in the art, technical scheme described in foregoing embodiments still can be modified by it, or wherein portion of techniques feature is carried out equivalent.All within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
Claims (2)
1. the permanent magnet sheath of a magneto, it is characterised in that coating one layer of heat-insulation protecting jacket outside the magnet ring of magneto, described protective jacket is made of ceramic materials.
The permanent magnet sheath of magneto the most according to claim 1, it is characterised in that the thickness of described protective jacket is 0.8 ~ 1.5mm.
