Drives Division Profile

SPEL, a.s., Drives Division, specializes in the regulation and control of electric motors in all areas of industry. We can apply the Variable Frequency Drives and Soft Starters for AC motors. We work in heating stations, power plants, water & waste water technologies, mining industry, metallurgy, cement plants, in the chemical industry, oil industry, ventilation of buildings etc.

Mostly we solve drives applications with the convertors for conveyors, pumps, fans, compressors, centrifuges, mining giant excavators, digging deep mine hoists. We are dedicated to propose special and interesting drives applications like braking motors & energy recuperation via power feedback units, torque and position control for lift applications, parallel motors operation (Load Sharing), the sequential switching one frequency converter to one and to the others motors and transfer each motor to the bypass without stopping the technology (Synchronous Transfer), etc.

We supply Variable Frequency Drives and soft starters to suit specific application needs. We are successful in speed and torque control AC/DC electric motors in power ranges 0.1 kW to 25 MW, for voltages 230 ÷ 11 kV. We successfully put into operation our first application of the MV Variable Frequency Drives in y.2001. For more detailed ideas about our experiences see Drives Division references.

We offer solutions. Speed control of the pumps and fans brings significant energy savings and therefore certainty a return on investment. Frequency converters extend the lifespan of mechanical components on conveyors.

We provide complete implementation of all related activities, including design and production, supply LV and MV switchgear, transformers, motors and other accessories, assembly, supply control system, creation of application software and visualization, communication and data networks, equipment control rooms, etc.

Our work does not end with the sale and commissioning of the equipment supplied. We use our own drives experts. We provide end user training. We learn designers and technology engineering. For the key drives and significant application we do drive support throughout their lifetime. We guarantee customer service 24/7 at all supplied by us LV or MV frequency converter and Soft Starters and other devices.
