Description
IR’s HiRel Digital Sensorless Motor Drive Module is a
complete digital speed/torque controller ideal for
applications demanding efficient operation in a compact
and rugged package such as fuel pumps, fans, and
compressors. This control is supported by the latest
hardware motion control technology from IR, including
the Servo Designer_TM tools. No software code
development is required due to its pre-configured
Motion Control Engine.
The HiRel Motor Drive Module contains IR’s advanced
iMOTION_TM Motion Control Chipset with monolythic Gate
Driver ICs and state of the art 100V MOSFETs enabling
simple and cost effective design of high reliability
speed controls.
