Product Description
110 Series Explosion-Proof Permanent Magnet Motors
Product Overview
The WHEATSTONE 110 Series Explosion-Proof Permanent Magnet Motors are designed for hazardous industrial environments where explosive gases, vapors, or dusts may be present. Featuring advanced permanent magnet technology combined with robust explosion-proof construction, these motors ensure high efficiency, compact size, and superior reliability while maintaining compliance with global safety standards such as IECEx, ATEX, and China’s Ex certifications.
These motors are ideal for applications where precise control, high power density, and energy efficiency are critical, especially in industries such as oil & gas, chemical processing, mining, and hazardous material handling.
Key Features
Explosion-Proof Safety – Flameproof enclosure prevents ignition of explosive atmospheres, meeting Ex d IIB T4 Gb or equivalent classifications.
High Efficiency Design – Permanent magnet excitation reduces copper losses and improves energy efficiency.
Compact and Lightweight – Smaller frame size with higher power density compared to conventional induction motors.
Wide Speed Control Range – Stable performance across variable load and speed conditions.
Rugged Durability – High-strength housing, anti-corrosion treatment, and reinforced insulation for harsh operating environments.
Low Maintenance – Permanent magnet structure minimizes wear components, reducing servicing needs.
