Abstract
The utility model relates to a permanent -magnet machine rotor starting system. Starting system include solid rotor, magnet steel, alinco assembled groove, separate the magnetic system, damping ring, slot wedge, additional starting system, additional starting system include a plurality of cage strip and a plurality of cage strip mounting grooves that start of starting, a plurality of start the cage strip inlay respectively a plurality of start cage strip mounting groove in, the cage strip mounting groove that starts set up on the alinco assembled groove, set up two cage strip mounting grooves on the alinco assembled groove between two adjacent magnet steel respectively, the solid rotor both ends will start cage strip and slot wedge through the damping ring and adopt riveting or welded mode to connect. The utility model discloses a change and start angle, quantity, the degree of depth that the cage strip was arranged, reduced direct axis reactance xq value, increased d -axis reactance xd value for xqxd's ratio reduces, reduces motor braking torque and reluctance torque in the motor starting procedure, has improved the starting performance of motor.
Description
Technical field
The utility model relates to a kind of permanent magnet machine rotor starting system.
Background technology
Permanent-magnet machine is because its power savings is given prominence to, it may also be useful to more and more extensive. The rotor of solid-rotor permanent-magnet motor is by ferromagnetic solid rotor body, form every magnetic system and additional starting system, and its structure is divided into solid rotor body, every magnetic system and additional starting system three parts. The tradition of solid rotor permanent magnet motor rotor adds starting system: on solid rotor top layer along the circumferential direction, cage bar is started in uniform one of each face, pole, the mode riveted or weld is adopted to carry out being connected to form a loop system damping ring and starting cage bar and slot wedge in two ends of rotor, in motor starting process, play raising starting performance. The constructional feature having again rotor, in the design process, quadrature axis reactance xq is much larger than direct axis reactance xd, and in starting process, the retarding torque of motor is big, and electric motor starting there will be shake instantaneously, reduces the starting performance of motor.
Practical novel content
The utility model in order to overcome the above problems provide a kind of structure simple, reduce retarding torque, reduce magnetic resistance torque, improve the permanent magnet machine rotor starting system of motor starting performance.
The technical solution of the utility model is: described starting system comprises solid rotor, magnet steel, alinco assembled groove, every magnetic system, damping ring, slot wedge, additional starting system, described additional starting system comprises some starting cage bars and some starting cage bars install groove, described some starting cage bars are embedded in some starting cage bars respectively and install in groove, described starting cage bar is installed groove and is arranged on alinco assembled groove, the adjacent alinco assembled groove between two magnet steel arranges two cage bars respectively groove is installed, the mode starting cage bar and slot wedge employing riveted joint or welding is connected by described solid two ends of rotor by damping ring.
Described cage bar is installed groove and is extended inside the lateral of solid rotor outer surface.
The utility model starts the angle of cage bar layout, quantity, the degree of depth by change, reduce quadrature axis reactance xq value, increase direct axis reactance xd value so that the ratio of xq/xd reduces, reduce the mechanism of power generation dynamic torque in motor starting process and magnetic resistance torque, it is to increase the starting performance of motor.By TXCY250M-12/22 rotor structure for permanent magnet motor being improved the locked-rotor torque simultaneous test of front and back, it can be seen that starting performance is greatly enhanced. The locked-rotor torque multiple improving front motor is 2.38, and the locked-rotor torque multiple improving rear motor is 2.78, and the vibration in starting process simultaneously also significantly reduces.
