Multi-phase Motor Controls

Multi-phase motors and drives are used in applications where efficiency and long life are necessities, such as for food service equipment, HVAC systems and high duty-cycle motion systems.

The EC105 and low voltage EC107 are analog trapezoidal brushless DC (BLDC) motor drives and the EC109 is a digital multi-phase drive designed to be used for three-phase AC induction motors as well as BLDC motors.

Features for our Multi Phase Controls:

  • Single, multiple or ranged voltage (85-265 VAC or 12-48 VDC)
  • Broad range of load current options
  • Two quadrant and four quadrant control
  • Over-current monitoring
  • Speed feedback for closed-loop precision
  • Custom user interfaces
  • Soft start, coasting and braking control
  • Operating temp -40 to 85 ºC and beyond
  • RoHS
  • CE compliant options including EMI
  • Quick time to market
  • Customized designs

LCR has developed easily-customized demonstration boards to reduce project start-up time. Contact an LCR sales representative for information on how to obtain a sample.
