Drive Start

IGBT Based Medium Volatage Soft Started - Up To 6.6KV, 500A

The first of its kind IGBT
based Medium Voltage Soft Starter
Ratings: up to 6.6KV, 5MW
Introducing the DriveStart, the first of its kind, IGBT based Medium Voltage Soft Starter, optimized for applications that require low starting current and/or a high starting torque. The cutting edge design results in significant savings in costs, energy and space while meeting high demand application requirements

Optimized for applications that require a low starting current and/or a high starting torque


Saving costs, energy and space while meeting top performance requirements

  • Provides full torque start
  • Starts at nominal motor current or lower
  • Enables motor starting from weak electrical networks
  • Reduces motor heat at start enabling use of standard motors.
  • More economical than a Medium Voltage VFD, yet providing similar soft start and soft stop features
  • Integrated bypass ensures no energy loss during operation, reducing energy waste and operational costs
  • Peak demand reduction
  • Streamlined design translating to at least 50% reduction in space equirements vs. a VFD with comparable performance

Technical specifications

  • Input voltage – Up to 6.6kV 50/60Hz +10% -15
  • Power range – Up to 6.6kV, 5MW
  • Mains starting current – 10% to 120% of motor rated current
  • Numerous number of starts
  • Starting torque – Up to 160% of motor rated torque
  • Internal synchronization system (bypass), from DriveStart to mains and back
  • Soft Start and Soft Stop
  • Multi-start capabilities
  • Electronic Potential Current Transformer (EPCT) voltage and current measurements via fiber optics
  • Integrated Data Logger and wave form capture for all major system signals including current and voltage for remote diagnostics and failure analysis
