M Rutty & Co. has launched a RoHS-compliant four-quadrant amplifier engineered to optimise the performance of brushless motors where efficiency, high acceleration and safety are of primary significance.
According to the company, the amplifier can be customised to various specifications by programming the level of current protection and PI regulation parameters.
With a compact footprint of 92 x 72 x 16mm and weighs just 45 grams (1.5 oz), the amplifier is suitable for portable equipment applications where size and weight are significant to the design.
A broad supply of voltage ranges of 5.5 — 50 V enables accurate control of Portescap’s 16-30mm brushless motors at speeds up to 90,000 rpm,
providing continuous current output of 3 amps, and maximum current output of 12 amps.
Thermal, short and over current protection are included as standard, while an optional start up current limitation feature helps protect surrounding equipment, according to the manufacturer.
An external temperature sensor can be connected to the amplifier to protect applications from overheating.
