Abstract
The utility model discloses a magnetic encoder with an adjustable magnetic pole angle and a permanent magnet synchronous motor using same. The magnetic encoder comprises an encoder main body, at least two fixing holes are arranged on the encoder main body, the fixing holes are circular arc shaped strip holes, and the centers of the circles of the circular arc shaped strip holes are coincided. In the utility model, the magnetic pole angle of a motor can be conveniently adjusted, the magnetic pole angles are unified before leaving factory, under the condition that the production cost of the magnetic encoder and the permanent magnet synchronous motor using the magnetic encoder is not increased, the installation, usage and after-sale service of the motor and a drive control system of the motor are very convenient and simple, the cost of the installation usage and the after-sale service is greatly reduced.
Description
Technical field
The utility model relates to a kind of magnetic coder of adjustable magnetic pole angle and uses the permagnetic synchronous motor of this magnetic coder.
Background technology
Permagnetic synchronous motor is used more and more widely owing to good control and servo performance.And the scales that is used for detection position and speed on the motor is an encoder, photoelectric encoder, resolver, magnetic coder etc. are arranged, constitute by magnetic induction part and treatment circuit as existing magnetic coder, in use, be fixed on motor case or the end cap, back magnetic coder magnetic induction part is installed has a relative position of determining with magnetic grain on the motor shaft, and we call magnetic pole angle to it.
The present existing mode that installs and fixes: the magnetic grain is installed on the motor shaft, and magnetic coder is installed on electric machine casing (being end cap or casing) by two fixing screw holes and goes up fixing inactive.Because the restriction of technology, the absolute position of the magnetic induction part of magnetic coder and motor magnetic grain must be discrepant, and the magnetic pole angle of the motor that therefore dispatches from the factory is all different.Every like this cover controller all needs to detect magnetic pole angle and learns drive motors normally, and motor and control system are used inconvenience, and the non-constant of interchangeability, for later repair and maintenance work brings great inconvenience.
Summary of the invention
The purpose of this utility model is to overcome the defective of prior art, a kind of magnetic coder of adjustable magnetic pole angle is provided and uses the permagnetic synchronous motor of this magnetic coder, the utility model can be regulated the magnetic pole angle of motor more easily, make the magnetic pole angle of motor when dispatching from the factory unified, thereby do not increasing magnetic coder and using under the permagnetic synchronous motor manufacturing cost situation of this magnetic coder, make installing and using of this motor and driving control system thereof become very simple and direct, greatly reduce and install and use and after service cost with after-sale service.
Its technical scheme is as follows: a kind of magnetic coder, comprise the encoder main body, and on the encoder main body, be provided with at least two fixing holes, described fixing hole is the circular arc cylindrical void, the center of circle of each circular arc cylindrical void overlaps.
Adopt the structure of the permagnetic synchronous motor of this magnetic coder to be:
A kind of permagnetic synchronous motor comprises electric machine casing, magnetic coder and hold-down screw, is provided with at least two fixing holes on the encoder main body, is provided with installing hole at electric machine casing, and described fixing hole is the circular arc cylindrical void, and the center of circle of each circular arc cylindrical void overlaps; Hold-down screw is fixed on magnetic coder on the installing hole of electric machine casing after passing the circular arc cylindrical void.
Further improvement to aforementioned schemes describes below.
Described encoder main body is a disc, and the center of circle of each described circular arc cylindrical void overlaps with the center of circle of encoder main body.
Described circular arc cylindrical void is two, is symmetrical arranged along the center of circle of described encoder main body.
In sum, the utility model has the advantages that: because the encoder main body is provided with the circular arc cylindrical void, magnetic coder is installed on the electric machine casing, magnetic coder is rotated, it is the relative angle between the magnetic grain on scalable magnetic coder and the motor shaft, and then the magnetic pole angle of motor regulated, make the magnetic pole angle of motor when dispatching from the factory unified, thereby do not increasing magnetic coder and using under the permagnetic synchronous motor manufacturing cost situation of this magnetic coder, make installing and using of this motor and driving control system thereof become very simple and direct, greatly reduce and install and use and after service cost with after-sale service.
