1) simplified installing mechanism:
Be used for replacing former asynchronous machine, turbine and worm and clutch through making of permagnetic synchronous motor, when having reduced the space of installing, simplified mounting structure, improved the installation exercise time, increased efficient.
2) reduced the trouble point:
Be used for reducing the use of external outer device through making of encoder, reduced the use of wiring terminal, this has just meaned and has reduced the corrective maintenance point.
3) increased application life of lever gear door:
Chain drive with bringing synchronously before replacing has hard connection to change into and is flexible coupling, and has reduced the mechanical degree of wear, has improved the service time of lever gear door.
Description of drawings
Fig. 1 is the systematic schematic diagram of the lever gear door control device that drives of a kind of permagnetic synchronous motor of the utility model.
The specific embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Consult Fig. 1, the systematic schematic diagram of the lever gear door control device that a kind of permagnetic synchronous motor of the utility model drives replaces limit switch with the magnetic induction encoder; The magnetic induction encoder is installed on the motor bonnet, and is concentric with rotor, and inductive magnetic steel is pre-buried on machine shaft; Through the running of rotor, magnet steel rotates with the same center of circle with respect to the magnetic induction encoder, magnetic induction encoder output PA; PB and rotor angle signal are input to motor pole position and speed calculation module, calculate motor pole position θ and actual speed ω; Through obtaining U, Z behind the SVPWM module arithmetic, V, Y, W, three groups of six pulsewidth voltage signals of Z; Three groups of totally six pulsewidth voltage signals input motor drive modules by motor drive module output motor A, B, C three-phase alternating voltage, drive permagnetic synchronous motor and accomplish the action of switch door.This system adopts speed and current double closed-loop algorithm that permagnetic synchronous motor is carried out vector controlled, reaches the control effect.
The foregoing description is technical conceive and the characteristics for the utility model is described just, its objective is to be the content that lets the one of ordinary skilled in the art can understand the utility model and to implement according to this, can not limit the protection domain of the utility model with this.The variation or the modification of every equivalence of having done according to the essence of the utility model content all should be encompassed in the protection domain of the utility model.
