Explosion-Proof VFD Core Unit 37–1000 kW
The explosion-proof core carries the variable frequency drive (VFD) electronics that mount inside certified explosion-proof enclosures, rated 37–630 kW at 380 V and 55–1000 kW at 660 V or 1140 V. V/f, SVC and FVC control with 150% overload for 60 s serves hoists, tensioners, belt conveyors and winches in hazardous areas.

Product Description
Hazardous-area machines cannot host a standard VFD, so integrators mount certified explosion-proof enclosures and fit the drive core inside. This core unit is built for exactly that: it carries the full V/f, sensorless vector (SVC) and closed-loop vector (FVC) control platform, with 150% overload for 60 seconds to break away loaded hoists and belt conveyors.
Power spans 37–630 kW at 380 V, 55–1000 kW at 660 V and 55–1000 kW at 1140 V, covering both standard mining networks and higher-voltage sites. It runs PM synchronous and asynchronous induction motors, and typical applications include hoists, tensioning stations, belt conveyors and winches where flameproof certification governs the enclosure while this core governs the motion.

FAQ about Explosion-proof VFD core
Is the enclosure included with the core unit?
The product listed here is the drive core (the electronics). Explosion-proof enclosures are certified per installation class and are supplied or approved separately by the system integrator — send us your enclosure drawings and we confirm the fit and wiring layout.
Which voltage should I choose for a mining site?
Match the mine's distribution: 380 V cores suit surface plants, while 660 V and 1140 V cores cut current draw for underground longwall and conveyor systems. Tell us the network voltage and motor list and we size the cores within 24 hours.
