380v – 1100v Variable Speed Drives (VSD)

Product description

B&F introduced its first 1100V water-cooled Variable Speed Drive (VSD) to the mining market nearly 20 years ago. Since then, our product development programme has resulted in a range suitable for all types of mining applications, with ratings up to 2MW at 3.3KV.
Coal Face Conveyor (AFC), Coal Clearance, Water Pumping Systems, and Underground Ventilation and Skip Controllers are all applications for our VSD units.

Key features

The ‘Stardrive’ 1100V VSD is designed to control an induction motor (voltage range 380V up to 1140V) from standstill up to its full speed, by either simple insertion into an LV supply cable (in-line), or by mating to a flameproof transformer to create a VSD Power Centre.

A rectifier, DC link and inverter combine to create the 3-phase output to the motor, with dedicated and sensitive protection for the output. Water cooling is employed to minimize the footprint of the unit.
B&F have a proven track record with a large global installation base of these units. Simple, rugged and reliable technology is employed to reduce potential down-time and therefore reduce cost of ownership.
