Slotless motors reduce inertia

22mm brushless motors provide fast acceleration and deceleration thanks to low inertia and a low mechanical time constant.
The latest range of 22mm brushless motors from Portescap weigh just 94g each and provide 50W power at up to 73,000rev/min.
They operate at a cool 25C and quiet 55dB noise level, and promise inertia as low as 0.23mmg2 - a 10% inertia reduction compared with previous, similarly sized motors from Portescap.
Additionally, a new internal design reduces motor length by 10% and vibration by as much as a 400%.
"Portescap's new 22mm brushless motors with slotless technology are a perfect complement to our 16mm models, and are an ideal solution for maximising the comfort of patients who use bilevel respirators", says Dave Beckstoffer, Portescap Product Manager.
Slotless motor technology provides fast acceleration and deceleration thanks to low inertia and a low mechanical time constant.
