Product Description

1MT0003 series 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 3836.1-2010/GB 3836.2-2010. The type of

protection for this motor is Ex d 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.



1MT0003 series 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.

1MT0003 Flameproof Three-Phase Asynchronous Motor



In many industrial and public industries, explosion hazards are ever- present, e.g. the chemicals industry, refineries, on drilling platforms, gas stations, feed manufacturing and sewage treatment plants. The risk of explosion is always present when gases, fumes, mist or

dust are mixed with oxygen in the air in an explosive ratio close to sources of ignition that are able to release the so-called minimum ignition energy.

To ensure safety in these areas, legislators in most countries have implemented appropriate stipulations in the form of laws and regulations based on national and international standards. Explosion- protected equipment is designed such that an explosion can be prevented when it is used properly.

Classification of zones
Areas subject to explosion hazard are divided into zones. Zoning is based on the presence time of explosive substances and probability of explosion. Information and specifications for classification of the zones are laid down in the following standards:
•GB 3836.14, IEC/EN 60079-10-1 for gas atmospheres
•GB 12476.3, IEC/EN 60079-10-2 for dust atmospheres
Furthermore, a distinction is made between various explosion groups as well as temperature classes and these are included in the hazard assessment.
1MT0003 Flameproof Three-Phase Asynchronous Motor

Depending on the particular zone and therefore the associated hazard, operating equipment must comply with defined minimum requirements regarding the type of protection. The different types of protection require corresponding measures to prevent ignition that should be implemented at the motor in order to prevent a surrounding explosive atmosphere from being ignited.

MESG, maximum experimental safe gap (for an explosive mixture). It's maximum gap of a joint of 25 mm in width which prevents any transmission of an explosion during 10 tests made under the conditions specified in GB 3836.11 and IEC 60079-20-1.

The smaller the MESG value, the higher the explosion-proof level of the equipment, and the more stringent requirements for the equipment. If the equipment can run under the IIC gas group, it also meets the requirements of IIA and IIB.


Noise levels for mains-fed operation
The noise levels are measured in accordance with DIN EN ISO 1680 in a anechoic room. It is specified as the A-valued measuring-surface sound pressure level Lpfa in dB (A). This is the spatial mean value of the sound pressure levels measured on the measuring surface. The measuring surface is a cube 1 m away from the motor surface. The sound power level is also specified as LWA in dB (A). Please find the noise value in technical data table, the specified values are only valid for totally enclosed fan cooling (cooling method: IC411) motor with no load at 50 Hz with no load, and the tolerance is +3 dB. While motor operating 60 Hz with no load, the values are approximately +4 dB (A) higher.
Vibration
1MT0003 rotors are dynamically balanced to severity grade A using a half key. Table below contains the effective vibration values for unloaded motors. Vibration grade B can be provided as option.

Bearing Assignment
1MT0003 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.

When the motor runs outside of normal conditions, the bearing life will be reduced, such as the following conditions.
■When motor runs beyond the rated speed, the increase of motor vibration will result in the extra radial and axial force on bearing. This will reduce the life of bearing;
■When the motor vibration increase due to the environment or other equipment, the bearing also will endure more radial and axial force. This also will reduce the life of bearing;

Connection box
The connection box is located on the top of motor housing as standard, and can be rotated by 4×90º to allow for cable entry from each direction. When selecting the entrance to the motor drive end, please notice whether there is enough space in front of the installation for the cable line. For the standard connection box with hoop gland, the motor of FS 80~225 has one hoop gland, and the motor of FS250~355 has two.



Motor protection

Anti-condensation heater
Motors whose windings are at risk of condensation due to the climatic conditions, e.g. inactive motors in humid atmospheres or motors that are subjected to widely fluctuating temperatures can be equipped with anti-condensation heaters (Option code: Q04).
Anti-condensation heaters must be switched off during operation. When motor shut down, the heaters must be switched on.
The electrical parameters of anti-condensation heaters are shown in the following table.

Motor thermal overload protection
Motor thermal protection means to use of thermal protectors and thermal detectors incorporated into the stator windings or placed in other suitable positions in motor in order to protect them against serious damage due to thermal overloads.
The order variants for motor protection are coded with letters in the 15th position of the Motor Order No., or ordered with Option code.

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.

Voltage and Frequency
IEC 60034-1 differentiates between Category A (combination of voltage deviation ±5 % and frequency deviation ±2 %) and
Category B (combination of voltage deviation ±10 % and frequency
deviation +3 % / -5 %) for voltage and frequency fluctuations. The motors can supply their rated torque in both Category A and B. In Category A, the temperature rise is approximately 10 K higher than during normal operation.
