Introduction
This flameproof motors is newly designed totally enclosed fan cooling (TEFC) high efficiency motor.
This series flameproof motor completely meet the standard of IEC 60079- 0:2017/IEC 60079-1:2017 and GB/T 3836.1-2021/GB/T 3836.2-2021.
The type of protection for this motor is Ex db IIB T4 Gb. And its efficiency fulfill efficiency grade IE3 (50Hz) of IEC 60034-30, and also Grade 3 efficiency of GB 18613-2020.
This series products have excellent performance, safe and reliable to use, simple and flexible installation, easy to maintain, low vibration, low noise.high-efficiency flameproof motors can be widely used in petroleum, chemical industry, oil and gas and other hazardous areas and places.
These motors are designed such that an explosion within the housing cannot result in an explosion in the environment.
The energy that is generated internally by an explosion is dissipated in the so-called "flameproof enclosure" so far that the energy is no longer sufficient for ignition outside the casing.
Bearing Assignment
This series motor are supplied with ball bearing as standard, these bearings are either sealed or regreasable type. Bearing design meets the requirements of explosion protection. Fixed bearing at NDE is as standard configuration for FS160 ~3 55 motors;For FS80 ~ 132 motors the bearings are floating, fixed bearing at DE can be ordered with option code L20.
If higher cantilever force on the shaft required, the increased cantilever bearing design (Option code: L22) should be considered.
As standard, FS80 ~ 250 motors are not with regreasing device, but re-greasing device (Option code: L23) can be configured in FS160~250. FS280 ~ 355 motors with regreasable bearing and regreasing device is configured as standard.
Electrical design
Rated Output
1MT0003 motors rated output powers means that the motor runs under continuous duty S1 (IEC 60034 - 1) operation when operated at ambient temperature from -20 ºC to 40 ºC and at altitudes of up to 1000 m over sea.
Overload times
According to IEC60034, 1MT0003 series motors are designed to withstand overload capacity of 1.5 times rated current for 2 minutes at rated voltage and frequency.
Application
1MT0003 motors are suitable for pumps, fans, compressors, textile machine and mechanical machine applications where variable or constant speed is required.
