BEI Kimco’s frameless motor part set design allows for the motor to be fully integrated within the customer assembly resulting in the highest ratio of torque to volume.
In this configuration, the motor’s rotor and stator are housed within the customer’s “next higher” assembly utilizing a common shaft and bearing system. This results in increased coupling efficiencies, and reduced system size, weight, and cost. The high magnetic pole count pancake “torquer” motor produces exceptionally low cogging for smooth low-speed operation and high-accuracy positioning applications.
Features
- Highest energy product permanent magnet rotor design for improved efficiency
- High pole count rotor for smooth operation
- Proprietary magnetic circuit design for optimal efficiency
- Low torque ripple
- Encapsulated Stator assemblies for improved thermal performance
Applications
- Medical equipment
- Industrial equipment
- Aerospace & Defense

Frameless voice coil actuators (VCA), also known as unhoused VCAs, are sold in pairs, featuring both the coil and the field assemblies, which are required to be aligned within the customer’s application. Frameless VCAs are the most cost-effective and versatile types of linear actuators, allowing customers to integrate them into their systems in a way that is best suited for the application.
VCA technology features many inherent advantages, such as direct drive, zero backlash, and cog-free operation for accurate motion, as well as high acceleration and the use of a single phase.
Features
- Capable of withstanding billions of cycles of use
- Constructed with high-energy product rare earth magnets
- Moving coil and moving magnet designs available
- Wide offering of standard products, reducing lead time and cost
Applications
- Medical equipment
- Industrial equipment
- Aerospace & Defense

Semi-housed voice coil actuators (VCA) enhance the basic frameless VCAs by adding both a shaft and self-aligning bushings to the unit. The lead wires have also been upgraded to a high-flex variant, allowing for added protection from wear and tear. Various shaft options are available depending on the size of the actuator, including both external and internal threading, as well as a standard smooth shaft.
Features
- Precision shaft with multiple options available
- Zero-cogging and backlash-free
- Life tested in excess of 500 million cycles
Applications
- Medical equipment
- Industrial equipment
- Aerospace & Defense

A fully housed voice coil actuator (VCA) further expands upon the idea of the semi-housed VCA, incorporating the self-aligning bushings and shaft, but fully captures the coil assembly to keep it concentric with the field assembly, adds an internal flex circuit to protect external moving wires and limits the axial travel on both ends of the stroke.
As a single piece, the linear actuator can be mounted on one side and does not require a customer-supplied alignment system, making it easy to integrate into applications. Housed voice coil actuators feature all the inherent advantages of VCA technology, such as direct drive, zero backlash, and cog-free operation for accurate motion, as well as high acceleration and the use of single phase.
Features
- Designs available with magnet springs and/or latches
- Different shaft options available
- Housing offers additional mechanical and environmental protection
- Single unit that is more easily integrated into customer applications
- Life tested in excess of 500 million cycles
Applications
- Medical equipment
- Industrial equipment
- Aerospace & Defense

The Cylindrical Housed Linear VCA with an Integrated Position Sensor is a housed VCA with an integrated Hall effect sensor. This convenient design enables users to run the actuator in a closed loop, allowing them to directly control the velocity, position, acceleration, and/or oscillation of the shaft. In applications where high speed, high reliability, extreme accuracy, and superior performance are vital, this actuator is the perfect match.
Sensata’s VCA Developer’s Kit pairs this VCA with an integrated sensor with a controller, software, and cables to allow customers to quickly develop an actuation system and demonstrate a working design concept.
Features
- Easiest VCA to integrate into customer applications
- Resolution of up to 10 microns
- Absolute analog output
- Compatible with several DC servo drive controllers
- Life tested in excess of 500 million cycles
Applications
- Medical equipment
- Industrial equipment
- Aerospace & Defense

Rectangular voice coil actuators (VCA) are linear VCAs just like the cylindrical models but are often used for applications that require a higher force and/or a longer stroke. Due to their shape, they can be designed to fit into tighter or thinner systems or optimized for their sheer power and high speeds. Rectangular voice coil actuators feature all the inherent advantages of VCA technology, such as direct drive, zero backlash, and cog-free operation for accurate motion, as well as high acceleration and use of single phase.
Features
- Zero friction caused by moving parts
- Ideal for high-acceleration applications
- Offers higher forces than cylindrical actuators based on their size
Applications
- Medical equipment
- Industrial equipment

Rotary voice coil actuators (VCA) are ideal for high acceleration applications that require angular movement. There are two types of designs available: Cylindrical and arc-segment. Cylindrical models are typically used in long-stroke applications, whereas arc-segmented designs are better suited for short-stroke and precise positioning.
Rotary actuators feature all the inherent advantages of VCA technology, such as direct drive, zero backlash, and cog-free operation for accurate motion, as well as high acceleration and the use of single phase.

The Airpax™ SNAPAK® Series combines the functions of three separate components: power switch, fuse, and fuse holder. To the OEM, this means that only one item has to be mounted instead of three. Less assembly is required, inventory is cut by two-thirds and greater panel density is obtainable with less clutter.
Since the SNAPAK® is snap-acting, it assures the immediate opening and closing of the contacts. Its design also prevents operator “teasing” of the contacts and minimizes arcing. SNAPAK® circuit protectors are UL Recognized as supplementary protectors per UL STD. 1077, CSA Certified as supplementary protectors per CSA STD. C22.2 No. 235, TUV Approved as circuit breakers for equipment per STD. EN 60934, CCC Approved (customer must request the product be manufactured in China) and CE Compliant.
Features
- Combines functions of power switch, fuse, and fuse holder
- Can be operated at either DC or 50/60Hz
- Variety of handles and actuators
- Quick-connect terminals available
Applications
- Office appliances
- Electronic data processing
