BEI Kimco

BEI Kimco is a brand of Sensata Technologies. Solving unique challenge requirements for motion control in industrial, aerospace/defense, medical and transportation applications is the core strength of BEI Kimco. Since 1974 BEI Kimco has earned the reputation for superior durability and reliability in brushless dc motors (BLDC), BLDC motor controllers, linear voice coil actuators, rotary voice coil actuators, and voice coil actuators with integrated position sensors.

At BEI Kimco, we integrate our expertise with customer requirements in motion control devices. Latest technologies range from voice coil actuator systems wtih position sensors, to providing direct drive actuation for applications from factory automation, to low-bandwidth torquers, ideal forgimbal drives, robotics and other stabilized platform applications. It means faster, quieter, more reliable devices for semiconductor and medical equipment where throughput and life itself are critical to success.

At BEI Kimco, we manufacture a comprehensive line of high performance fractional horsepower brushless DC Motors (BLDC) that are currently manufactured in sizes from 1.1" up to 20” in O.D. diameter and capable of operating at speeds in excess of 70K RPM. We also manufacture voice coil Actuators (VCA) available in both Linear and Rotary versions. Linear versions offer strokes up to 4” and forces up to 225 Lbs. Rotary versions are available with up to 30 degrees of total excursion angle and a maximum torque of 1000 oz-in. Both offer infinite positioning capabilities for your application.

We remain deeply committed to solving your application challenges through technological innovation. Take our Spherical Voice Coil Actuator for example – Roll Pitchand Yaw motion in one device. Think of the possibilities. With our brushless DC noise attenuation patent – perhaps you may find it to be the right answer.

BEI Kimco maintains its high level of manufacturing repeatability with ISO9001:2008 Registration. Our commitment to ongoing product improvement ensures consistently superior products that optimize performance, size, and cost.

BEI Kimco has become the supplier of choice worldwide for the most cost-effective and reliable solutions. BEI Kimco is dedicated to taking technology to the limit. At our Business Development & Technology Center, we challenge ourselves to create innovative ways to meet new application needs. BEI Kimco has developed brushless DC motors to operate virtually noise-free, ideal for user confidence in quiet operating systems and patient care applications.

Our products can be found in a broad range of industrial applications including office/factory automation, medical science/lab instrumentation, optics, fast beam steering, wire bonding equipment, electronics/semiconductor equipment, and renewable energy. You can also contact us for your ITAR defense/aerospace applications like communications and stabilization/target acquisition.


BEI Kimco has merged leading-edge capabilities and cost-effective manufacturing know-how with highly personalized applications expertise. This combination has propelled BEI Kimco into market dominance where we have remained a leading manufacturer of brushless DC motors and linear and rotary voice coil actuators since 1974.

In that time, we have put thousands of BEI Kimco motors and actuators into products in markets ranging from optics, fast beam steering, and electronics/semiconductor equipment to office, factory automation equipment and automotive equipment.


BEI Kimco is an established manufacturer of motion control products used for military, aviation and space systems. BEI Kimco was chosen as the sole source supplier for the torque motors that will be used on the battlefield imaging platform. This system will be supplied for use on the mobile gun system that is currently being built into a military vehicle platform, a 19-ton wheeled armored vehicle.

BEI Kimco is a pioneer in the development of direct-drive, or "Frameless," torque motors (torquers). These compact, high performance motor part-sets use high slot-to-pole ratios and couple the motor's rotor directly to the load, without the need for gearing. This approach eliminates errors due to mechanical friction/backlash and is ideally suited for applications where rapid starts/stops, high acceleration and low speed precision motion are required. The brushless versions of this technology are being used in a variety of smart weapons platforms, medical applications.
