TECHNICAL DATA

Explosion-Proof Motors – MAK Series

Ex db, Ex db eb, IIB and IIC, II 2G and II 2GD, T3/T4/T5/T6

Introduction

The Euromotori MAK Series explosion-proof motors are designed in full compliance with ATEX Directive 94/9/EC, which defines the essential safety requirements for equipment intended for use in potentially explosive atmospheres.
Compliance with these ATEX safety standards is confirmed by the CE certificate issued by CESI, Notified Body No. 0722.

Definition

An explosion-proof and flame-proof motor (Ex db, Ex db eb) is a rotating electrical machine specifically engineered to operate safely in hazardous environments where explosive gases, vapors, or flammable fumes are present — without posing a risk of ignition or internal damage.

These motors are designed to meet the following safety principles:

Explosion-proof: The housing resists internal explosions without cracking or rupturing, preventing external hazards.
Flame-proof: The motor’s enclosure prevents flames or hot gases from escaping, even under fault conditions or when exposed to high ambient temperatures.

Standards Compliance

Euromotori MAK Series motors are manufactured in accordance with the following European CENELEC standards:

EN 60079-0:2006 (General requirements)
EN 60079-1:2004 (Flameproof enclosures “d”)
EN 61241-0:2006 (Protection by enclosures for dust atmospheres)
EN 61241-1:2004 (Protection by enclosures “tD”)

As a result, these motors are fully suitable for installation in hazardous areas, as defined in EN 60079-10, EN 60079-14, and EN 60079-17 standards.

MK vs MKC Series – What’s the Difference?

While the MK and MKC single-phase motor series share the same foundational strengths—such as aluminium housing, IP55 protection, and permanent capacitor operation—their designs reflect different priorities:

MK Series begins at frame size IEC 71 and is engineered with a higher starting torque, making it ideal for demanding or complex applications requiring extra breakaway force. It features a natural unpainted aluminium housing, offering a distinctive clean look.
MKC Series, by contrast, starts from IEC 56 and includes removable feet and a reversible terminal box, offering greater flexibility for tight or custom installations. MKC models are also available in 2-, 4-, and 6-pole versions, whereas MK motors follow the more typical single-phase pole range.

Each series is tailored to different installation needs—MK where performance under load is critical, and MKC where space, mounting, or modularity are key.
