Product Overview
Compact potted torque
The CubeMars RI85-PH KV85 encapsulates its windings and internal components with potting compound to boost resistance to vibration, thermal stress and environmental exposure, improving lifespan and stability.
An optimised electromagnetic design raises torque and power density by around 25 percent, while a thinner iron core keeps the overall size compact with a 52 mm through-hole for flexible frameless integration.
