SD2M

Drive Amplifier With 3-level Technology

SD2M opens up new opportunities for the motor design

Drive amplifiers of series SD2M are optimized for complex automation tasks in the high-speed sector – regardless of whether synchronous or asynchronous motors are used. The devices allow easy and flexible implementation of sensorless applications as well as applications with speed sensor. The high-dynamic sensorless vector control combined with highest speeds offers a whole new range of applications.

Applications:

  • Turbo blowers for wastewater treatment
  • Turbo blowers and turbo compressors for compressed air production
  • High-speed manufacturing spindles
  • Motor-driven high-speed applications

Features:

  • Power output stage with 3-level technology
  • Rated power up to 367 kVA
  • Rotating field frequencies up to 2,000 Hz
  • Efficiency up to 98%
  • Extremely compact design
  • Switching frequencies up to 16 kHz
  • Liquid cooling by standard
  • Overload capacity of 25 %
  • Optimized for industrial applications
  • Control with or without a sensor for asynchronous and synchronous motors
  • Integrated safety functions (e.g. STO)
  • Various options for the connection of the higher-ranking control: configurable analog inputs and outputs +/-10 V, RS232, CAN, configurable digital inputs and outputs, EtherCAT (CoE)*, Profibus (optional)

    *CoE = CAN over EtherCAT
