Customised slide and damper actuator for extreme operating conditions

Development of a unique and efficient slide valve and butterfly valve actuator in a highly demanding environment. From the motor and gearbox to the drive control system, ATEX, IECEx, CE and UL certification, and series production – all from a single source.

The challenge
The end customer required a drive that met the following criteria:

Use in ATEX and IECEx Zone 22
Ambient temperatures from 5 to 50°C
Very long service life with over 10 million cycles
High continuous and acceleration torques at low speeds
Minimal self-heating, maximum energy efficiency
Most compact design for installation in an existing device
Global approvals (ATEX, IECEx, CE, UL)

No such drive system was available on the market at that time. Only Antrimon succeeded in economically realising these requirements from concept to certified series solution.

The solution of Antrimon
Antrimon developed a completely customised brushless external rotor motor with integrated 2-stage planetary gearbox. The focus was on maximum torque at minimum speed, high energy efficiency and absolute reliability in tough continuous operation.

Typical areas of application

Dosing and filling systems in the food and chemical industries
Valve, flap and mixing drives in hazardous areas
Robotics and handling systems with limited installation space
Replacement for pneumatic actuators (energy-efficient, precise, quiet)

Technical highlights

Planetary gear: < 0.4° backlash
Service life: > 10 million cycles
Self-heating: < 10 °C in normal operation
Robust aluminium/stainless steel construction
Maintenance-free: no brushes, no oil changes

From concept to series production
Antrimon handled the entire development process in strict accordance with the safety and quality requirements of the relevant standards:

Feasibility analysis & concept development
Mechanical, motor and electronic design
Prototyping & validation under real extreme conditions
Certification process (ATEX, IECEx, CE, UL)
Industrialisation & series production

The interdisciplinary team and complete in-house development significantly reduced development time, costs and technical risks.

The result
The new drive is now a key performance component in the customer's end device.

It enables:

Significantly lower energy consumption compared to pneumatic solutions
Long maintenance intervals
Higher process reliability
Full certification for worldwide markets
A significant competitive advantage in global plant engineering

This makes Antrimon the only supplier worldwide that can economically realise such a motor in this form
– from concept to certified series solution.
