Servicing the electric motor sector

Second Quarter 2025 Editor's Choice Electrical switching & drive systems & components

Hexagon Electrical has expanded its manufacturing and service capabilities to meet the increasing demand for customised, high-performance electric motors in heavy engineering, hazardous industrial environments, and mining applications. Based in Brakpan, Gauteng, the company specialises in both flameproof and non-flameproof equipment. By combining mechanical precision, electrical expertise, and design innovation, Hexagon Electrical delivers robust, energy-efficient certified solutions that are tailored to meet specific customer requirements.

“Our broad product portfolio comprises motors and transformers, enclosures and switchgear, ventilation fans, scrubber fans and auxiliary equipment, as well as a full range of flameproof equipment compliant with SANS 60079 standards,” explains David Dyce, CEO of Hexagon Electrical. “The range of specialised Hexagon motors includes dual kW and dual speed AC motors, slip ring motors and water-cooled flameproof motors. Our portfolio includes flameproof and standard winch motors, traction motors, and pad mount motors suitable for heavy-duty mining applications.” All motors are offered with optional customisation in voltage, mounting, shaft configuration and thermal protection. The company also designs, supplies and services transformers, enclosures, ventilation equipment and auxiliary components for integrated system deployment.

“This robust equipment is engineered to ensure high performance and optimum safety in critical applications, including ventilation in hazardous areas, chemical processing, materials handling and underground mining.

“Through in-house design, manufacturing and testing facilities, our highly-skilled team offers a complete service lifecycle, including system design, motor rewinding, mechanical refurbishment, electrical testing and final certification.”

The company’s recent investment in test infrastructure enables motors to be evaluated at full load up to 460 kW and 6,6 kV. Flameproof inspection is conducted by accredited inspectors and all products undergo mechanical and electrical assessments prior to final assembly. A dedicated vacuum pressure impregnation (VPI) system and dual varnishing process ensure quality, durability and performance in extreme operating environments.

Hexagon’s facility is equipped with four production bays, each with dedicated lifting capabilities ranging from 5 to 25 tons. In-house machining, lamination punching, coil winding and dynamic balancing are all undertaken using modern equipment, including a 460 kW Schenk dynamometer and high-voltage test systems.

The manufacturing process is supported by proprietary design software developed in collaboration with the University of the Witwatersrand, enabling advanced simulation, stress verification and application-specific winding design.

Environmental and safety standards underpin the company’s operations which are fully compliant with SABS, SA Flameproof Association, SEIFSA, MASC and ISO technical standards. Motors and control systems are assembled in accordance with SANS 10242 and inspected against client specifications prior to dispatch. Each unit is supplied with a full data book, including balancing certificates, electrical test reports, records of the repair history and traceable calibration records.

Hexagon Electrical is led by David Dyce, whose technical expertise and dedication to quality assurance drive the company’s emphasis on performance, reliability, and long-term customer support. As a part of Montsi Investments, Hexagon focuses strategically on industrial resilience, providing manufacturing of new products and repair services to sectors where downtime and failure can result in significant operational costs.
