Miniature brushless slotless DC motors for demanding applications

Now available from Mclennan, Portescap's new 22ECP series brushless and slotless miniature motors feature optimised speed/torque performance characteristics in two length versions with 80W or 120W continuous output power. The new 22mm diameter motor particularly suits demanding speed and/or position controlled power transmission use where smooth operation, high precision, long working life and competitive costs are essential design considerations. The 22ECP is part of Portescap's patented Ultra EC range which is characterised by its superior power density factor. Typical applications include high performance power tools, precision actuators, automation equipment, robotics, and wherever high mechanical power and solid durability is required in a compact installation envelope. The newcomer is available in nominal lengths of 45mm and 60mm and can deliver up to 50mNm continuous torque - up to thirty percent more torque and twice the output potential of similar sized precision motors. The 24VDC motor with 40mm length (22ECP45) can deliver no load speeds of 8.37 or 15.7krpm, whilst the 60mm version (22ECP60) yields 8.05krpm. Alternative coil designs are available on request to match custom speed and voltage requirements. The 22ECP is available with or without hall sensors and the optional dual shaft version is fully compatible with Portescap's M-sense rotary encoders for servo controlled operation. The high-precision M22 series planetary gearbox range is a similarly a direct fit for compact high torque use up to 4Nm. Through its own design and manufacturing capability, Mclennan can also provide absolute encoders or other gear unit choices; or include the 22ECP as part of a customised miniature power transmission solution complete with motion controls.
