Portescap recently expanded its line of Ultra EC dc brushless and slotless motors with the introduction of the 35ECS. Available in two lengths, the 35ECS60 and the 35ECS80, the 35ECS is a two-pole, 35-mm diameter motor capable of continuous speeds of 40,000 rpm.
The 60-mm-long 35ECS60 can sustain a peak torque of 1.1 Nm and the 80-mm-long 35ECS80 can output a peak torque of 2.0 Nm. The new motor is built with a laser welded front flange to withstand the forces present during high-torque reactions. Portescap incorporated its patented Ultra EC coil technology for reduced core losses and improved torque without additional friction or brush wear. Customized options are available, including Hall-effect sensors, onboard temperature sensors, gearboxes, encoders, six different coil variations, and modifications to the mechanical interface. The motor is well-suited for fans and pumps, portable and battery-powered applications, or wherever a design is up against severe weight or dimensional constraints.
