Motor amplifier

With fully programmable features, a Hall sensor amplifier from M Rutty is specifically engineered to optimise the performance of Portescap’s brushless motors in applications where efficiency, high acceleration or safety are of primary significance.

All inputs and outputs are clearly identified to facilitate easy start-up in fewer than 10 mins.

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 16 mm and weight of 45 g, the device is suitable for portable equipment applications where size and weight are significant to the design.

A broad supply of voltage ranges of 5.5 to 50 enables accurate control of Portescap’s 16-30 mm brushless motors at speeds up to 90,000 rpm. It provides a continuous current output of 3 A and maximum current output of 12 A.

Thermal, short and overcurrent protection are included, while an optional start-up current limitation feature helps protect surrounding equipment (such as a battery pack).

An external temperature sensor (ie, motor case temperature) can be connected to the amplifier to protect an application from overheating.
