Description
Technical field
The utility model relates to elevator traction machine technical field, in particular to a kind of compact permanent magnetism synchronization gear wheel free elevator
Traction machine.
Background technique
Current market of real estate is in eruptive growth, room rate and land price rising all the way, many large- and-medium size cities
Even there is the case where an inch of land is an inch of gold, our government also appeals to advocate the intensive society of foundation continuous, under this form
High-rise and Super High becomes current real estate mainstream, therefore elevator has wider application, while also having newly to elevator
It is required that.On the one hand need to compress the installation space of elevator, in order to adapt to new situations, domestic and international elevator manufacturer is proposed machine room electricity
Elevator host is directly installed in hoistway by ladder, does not set up computer room occupied space individually, and this requires elevator hosts to accomplish
Slimming, lightweight, and parts to be maintained have be easy to detect, disassembly and can safeguard.On the other hand with modern society
Meeting middle-high building increases sharply, and elevator is more and more continually used in daily life, proposes to elevator driving more next
Higher requirement, drive system play control action to acceleration and deceleration, the stable operation of elevator, and the quality of drive system whether is direct
Influence the starting of elevator, stopping, acceleration and deceleration, leveling precisely and the indexs such as riding comfort.
The slimming of elevator host and is readily able under the target for realizing good control lightweight, and permanent-magnet synchronous is anodontia
Wheel traction machine is because its is small in size, fuselage is thin, is easily installed and can reliably control to obtain the favor of numerous domestic and international elevator manufacturers.
It is known that permanent-magnet synchnorous gearless dragging machine needs to realize drive and control of electric machine by encoder detection and identification rotor-position,
The reliability service of so encoder is the guarantee and premise that drive system well controls.To cope with new situations, new demand, existing skill

It is required that runing counter to.
2. traction machine main shaft is made hollow shaft, encoder is built in hollow shaft cavity, and encoder is by rotating axle portion (i.e.
Axis stretches connecting rod) it is connect with rotary body, encoder is fixed on main the tip of the axis nearby or near starting point, and this encoder is fixed
The advantages of mode is that axial dimension shortens.But the encoder of which is stretched connecting rod by axis and is connect with rotary body, axis stretches connecting rod
There is disturbance vulnerable to external force in the process moved with rotary body and encoder acquisition signal is caused to be made a fault, so that control
Jitter.Furthermore encoder is placed in hollow shaft cavity, at the scene installation and transportational process in, be easy foreign matter enter and
Encoder is damaged, encoder cisco unity malfunction is caused.
There are also above two modes to be only adapted to install a kind of encoder or photoelectric encoder or magnetic coder, may be selected
Property it is small, be not able to satisfy different controls requirement, versatility is poor.
3. a kind of permanent-magnet synchnorous gearless dragging machine disclosed in the patent No. 201611262429.3, while just there are two codings
Device installation position.Photoelectric encoder is that (i.e. connecting rod) connection is stretched by axis in which, and magnetic coder information collection is partially disposed in machine
On shell, and in being installed additional on rotating part by induction tape, complicated and poor reliability is made.
