Flameproof Permanent Magnet Motorized Pulley

Permanent magnet AC synchronous motor is a further development of permanent
magnet direct drive system, which integrates permanent magnet AC synchronous
motor with belt conveyor drive drum and truly realizes mechatronics. The VFD
compatible motor not only inherits the advantages of a permanent magnet direct
drive system, but also has the characteristics of further eliminating low-speed
coupling, occupying very little space, convenient installation, and
construction, etc..

Besides this kind of permanent magnet AC synchronous motor, we also have other
high-quality vfd for synchronous motor for sale.

What is a Permanent Magnet Synchronous Motor?
Permanent magnet synchronous motor is actually a kind of AC motor, its stator
operation is three phase difference AC, and the rotor is permanent magnet. But
the greatest advantage of this motor is that AC energy is provided by DC, which
can accurately control the motor and solve the life problem caused by brushes.

Permanent Magnet Synchronous Motor Theory
Permanent magnet synchronous motor is mainly composed of rotor, end cover and
stator. The stator structure of permanent magnet synchronous motor is very
similar to that of ordinary induction motor, The biggest difference between
rotor structure and asynchronous motor is that high-quality permanent magnet
poles are placed on the rotor. According to the different positions of
permanent magnets placed on the rotor, permanent magnet synchronous motor is
usually divided into surface rotor structure and built-in rotor structure.

Permanent Magnet Synchronous Motor Control
The asynchronous start-up process of permanent magnet synchronous motor can be
regarded as steady-state asynchronous operation at different speeds. During the
start-up process, when the stator winding is fed with three-phase symmetrical
alternating current of frequency, the air gap magnetic field generated rotates
at synchronous speed, and the alternating current of frequency is induced in
the rotor starting squirrel cage winding.

Features of the Permanent Magnet Ac Synchronous Motor
The outer rotor structure of permanent magnet ac synchronous motor has no
reducer mechanism inside, the permanent magnet synchronous electric roller
shaft is stationary and the outer rotor rotates when working;

The outer rotor permanent magnet is embedded and installed, which effectively
protects the permanent magnet, has no risk of falling off, and has high
reliability;
The low-speed coupling is omitted, and the transmission efficiency is higher;
The permanent magnet ac synchronous motor is a ceramic encapsulation with good
wear resistance.

Advantages of Permanent Magnet Synchronous Motor
The advantages of permanent magnet synchronous motor are as follows:

Permanent magnet synchronous motor itself has high power efficiency and high
power factor;

Permanent magnet synchronous motor has little heat, so the motor cooling system
has simple structure, small volume and low noise;

The system adopts totally enclosed structure, no transmission gear wear, no
transmission gear noise, no lubricating oil and no maintenance;

The permissible overload current of permanent magnet synchronous motor is large
and the reliability is significantly improved;

Application of Permanent Magnet Synchronous Motor
Permanent magnet ac synchronous motor is used on belt conveyors. It is widely
used in waste rock recovery in concentrator, steel slag treatment in steel
mill, iron removal from raw materials in cement plant, power plant, coal, port
and building materials industry
