Explosion-proof Permanent Magnet Motors
Explosion-proof motors use a flameproof enclosure to separate the electrical parts that may generate sparks, arcs and dangerous temperatures from the surrounding explosive gas mixtures, dust, fibers, etc.
Explosion-proof Permanent Magnet Motors
The motor can be used as a replacement for conventional asynchronous explosion-proof motors. Permanent magnet synchronous explosion-proof motors can replace the traditional asynchronous explosion-proof motors can be used in flammable and explosive places of a kind of motor. Its explosion-proof structure, explosion-proof principle and traditional asynchronous explosion-proof motors are completely similar or the same, and in full compliance with GB3836.2010 Explosive Environment “with electrical equipment standard family of related standards.
The rotor of this series of motors has damping windings, and at the same time, it has the self-starting ability of asynchronous motor and the characteristics of permanent magnet synchronous motor with large torque and high force energy index, and it has the advantages of high efficiency, small volume, low noise, low vibration, large temperature rise margin, reliable movement and long service life.
Advantages
High efficiency energy saving, Low temperature rise
