Acknowledging the need for smooth motor operation in precision positioning and actuation applications, BEI Kimco Magnetics (www.beikimco.com) has unveiled its latest BLDC Limited Angle Torque Model LAT40-48, which seamlessly eliminates disruption from cogging while delivering high peak force.
“The beauty of this limited angle torque is that it has absolutely zero cogging or detent which makes it ideal for stabilisation applications,” said Jim McNamara, Senior Applications Engineer at BEI Kimco.
“To have that kind of torque without cogging is quite unique to the market.”
A limited angle torque motor, the LAT40-48 motor features a rotor that has no preferred position. This feature helps the motor eliminate cogging, resulting to extremely smooth and consistent performance and making the motor ideally suited for applications that rely on uninterrupted operation, such as scanning, beam steering and stabilization platforms.
With a single phase winding, the new motor offers easy control, allowing a 30 degree excursion with no commutation. Featuring +/- 15 degree stroke and a peak torque of 21.5 Nm, the LAT40-48 motor utilises rare earth, high energy magnets to create 10.08 oz-in Watt power density.
Measuring only 100.0 mm in diameter and 100.0 mm in stack length, this Brushless DC Motor (BLDC) comes with fixed magnets and delivers all the advantages over brushed DC motors, which includes increased reliability, more torque per weight and watt (increased efficiency), longer lifetime, reduced noise as well as overall reduction of electromagnetic interference.
