The TA series gearboxes are a recognized best-seller for conveyor belt operations, especially in outdoor environments and mining applications, where durability and low maintenance are critical. A key feature of the TA series is the optional backstop, which prevents reverse rotation under load — an essential safety component in many conveying systems.
The VF and W series worm gearmotors represent industry benchmarks worldwide, combining state-of-the-art technology with uncompromising quality and renowned cost-effectiveness. Their intelligent design, enhanced by advanced materials and precision manufacturing, ensures long-term performance and flexibility for a wide range of applications.

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.
The powerful solution to all heavy duty drive problems
Compact, and yet extremely powerful, are the units of the 300 series. Their planetary drive train makes them the ideal choice for all the severe duty applications where shock loadings and impacts are more the rule than the exception. The product configuration is highly versatile, due to several options as far as the mounting, the gear layout, the output shaft and the motor interface. All the features are available for each of the 18 finely spaced frame sizes, spanning over the 1,000 – 1,400,000 Nm torque range. Finding the perfect match to any drive problem is therefore more than a wish, it is something users can safely rely on – always.
