Portescap N Series slotted brushless DC motors run at operating speeds up to 100,000rev/min to provide more power with less heat in a smaller package than comparable motors.
Danaher Motion has released the Portescap N Series of slotted brushless DC motors.
These motors are available in size 5, 6, 9 and 11 ideal for medical and electronic assembly applications where high speed is key, and in sizes 12, 14 and 15 for industrial applications where high torque is required.
N Series motors run at operating speeds up to 100,000rev/min to provide more power with less heat in a smaller package than comparable motors.
As an example, the operating temperature of a 22mm 50,000rev/min running motor has been reduced by 25C over previous models.
Maximum efficiency of up to 80% facilitates longer battery life for portable medical and industrial hand tool applications.
It also reduces energy consumption in applications such as electronic assembly and textile where equipment may be running hundreds of motors.
Additionally, a unique internal design minimises torque ripple for extremely smooth operation throughout the motor's operating range.
Available options include autoclavability features, a high-count encoder, resolver, custom shafts, shaft seals and high temperature ratings.
