Motors for use in mechanical smoke and heat exhaust ventilators

Product catalog summary

Overview: This document provides detailed information about VEM's three-phase asynchronous motors designed for mechanical smoke and heat exhaust ventilators. These motors are characterized by their versatility, modern design, productivity, robustness, reliability, and ease of installation and service.

Specifications: The motors are compliant with EN 12101-3 standards and are available in fire gas versions capable of withstanding temperatures up to 600 °C. They are based on the K21R/K11R series, with adaptations in insulation systems, bearings, and cabling to endure smoke and heat. The motors use materials that comply with temperature classes F, H, or 250 (IEC85) depending on expected temperature loads.

Technical Details:

Sizes: 56 – 355
Output range: 0.09 – 450 kW
Degree of protection: IP 55 (DIN EN 60034-5)
Cooling method: IC 411 (DIN EN 60034-6)
Construction types: IM B3, IM B35, IM B5, and derived types (DIN EN 60034-7)
Ambient temperatures: Shaft height 56 to 132 T: -20 °C to +40 °C; from shaft height 132: -40 °C to +40 °C
Fire gas classification: F200, F300, F400, F600 (DIN EN 12101-3)

Performance and Reliability: VEM's fire gas motors are designed to function like conventional fan motors under normal conditions and continue to operate reliably under high temperatures during a fire. They are tested and certified to remain operational for the duration specified in relevant standards or customer specifications. These motors have been proven in various major tunnel operations.

Fire Gas Classification: The motors are classified according to EN 12101-3 into classes F200 to F600, based on their ability to withstand specific temperatures for designated periods (1 hour at 200 °C for F200, 2 hours at 300 °C for F300, etc.).

Motors for use in mechanical smoke and heat exhaust ventilators-3

The fire gas motors from VEM are based on the proven basic design of the K21R/K11R series. Adaptation of the insulation systems, bearings and cabling connections enables them to withstand both smoke and heat. The motor insulation systems, in particular, are subjected to extreme heat in the case of a fire, which could even lead to decomposition of the materials. Thus, depending on the temperature loads to be expected, materials complying with temperature class F, H or 250 (IEC85) are used. The motors are connected by way of hightemperature- resistant cables or specially insulated single conductors....
