110 Series ATEX Explosion Proof AC Servo Motors

Product Overview

The WHEATSTONE 110 Series ATEX Explosion Proof AC Servo Motors is A high-precision drive motor specifically designed for space-constrained flammable and explosive environments, combining an ultra-compact 60mm frame size, explosion-proof safety certification, and the high dynamic response characteristics of a servo motor.

Key Features

Compact Size: With a side length of just 110 mm and a minimum axial length of 307 mm, the motor is ideal for precision equipment—such as semiconductor testing equipment and online analytical instruments—where internal space is measured in centimeters.

High Explosion-Proof Rating: Typical products meet the Ex db IIC T4 Gb rating. IIC is the highest group for gas explosion protection, making it suitable for environments containing the most hazardous gases, such as hydrogen and acetylene; The T4 temperature class ensures that the maximum surface temperature does not exceed 135°C.

Excellent Control Accuracy: Utilizing closed-loop vector control, repeatability can be consistently maintained within ±0.005 mm, with no loss of synchronization during 3,000 hours of continuous operation.

Electrical Parameters

ATEX Explosion-proof AC servo motor = **high-precision closed-loop control of AC servo motors** + **explosion-proof enclosure design**, used in hazardous areas where **flammable and explosive gases or combustible dust** are present (Zone 1/Zone 2 for gases; Zone 21/Zone 22 for dust). It enables precise positioning, speed regulation, and torque control, while also preventing internal electrical sparks and high-temperature surfaces from igniting explosive media.

First 、Oil, Petrochemicals, Oil and Gas, and Hydrogen Energy Industries

1. **Electric Valve Actuators**: For pipeline control valves and emergency shut-off valves, providing fast and precise positioning. Replaces pneumatic actuators and is used in hydrogenation units, hydrogen pipelines, and oil and gas transmission pipelines (Ex db IIC T4, suitable for hydrogen environments).

2. Reactor agitators, feed pumps, crude oil transfer pumps, offshore platform automation equipment, and explosion-proof AGVs for the oil and gas industry.

3. Hydrogen Energy: Hydrogen production, hydrogen storage, refueling mechanisms for hydrogen refueling stations, and hydrogen valve actuation. Hydrogen is classified as a Class IIC highly hazardous gas, requiring high-grade explosion-proof servo systems.

Second、Fine Chemicals and Pharmaceutical Industries

1. Chemical reactor agitation, precision feeding, sealed powder conveying, and filling equipment; Zone 1/2 environments involving solvent vapors (ethanol, acetone, ethyl acetate).

2. GMP pharmaceutical production facilities: automated feeding of solvents and flavorings and fragrances, requiring cleanliness, corrosion resistance, and explosion protection.

3. Ink and coating production lines, coating machines, and composite printing equipment (where solvent evaporation forms explosive mixtures).

Third、New Materials for Lithium-Ion Batteries

Production lines for lithium-ion battery anode and cathode materials: slurry preparation, enclosed powder conveying, batching, and coating. The site contains both **NMP organic vapors and conductive dust from graphite and lithium iron phosphate**, which generally requires **dual explosion-proof certification for gas and dust (Ex db IIC T4 + Ex tb IIIC)**.

Fourth、Spray Coating Industry

Robots for coating complete vehicles and automotive parts, reciprocating spray machines, and furniture spray painting lines. Solvent vapors generated during spray painting are highly flammable; explosion-proof servo motors are used in robot joints, paint metering pumps, and spray gun motion control to ensure precision in spray patterns and film thickness.

Why do you need a custom motor?

1)Global trade, market diversification, diversified consumer demand, the The trend of individualization is obvious, backing up to the upstream industry to have more special spare parts requirements for new processes and new processing equipment.

2)The World's future long-term national policy guidelines for supply-side reform, elimination of backward production capacity, environmentally friendly, energy-saving, intelligent and safe, the entire industrial environment are in transition, the original batch, large-scale production can not meet market needs.

3)Industrial homogenization competition is extremely serious, the survival environment is worrying; a large number of enterprises seeking change, in response to national policies, the trend of the times, close to customers, to solve customer personalization, targeted problems, personalization has become an important way of industrial production.

4)Electrification, automation, intelligence is the future trend, these can not be separated from the motor, so the future development trend of the motor industry is obvious, especially the personalized non-standard custom motor, market demand is more objective.
