KBM™ Series Frameless Motors
The KBM™ Series provides low- and high-voltage motors (120–480 Vac) designed to be directly embedded in your machine using the machine’s own bearings to support the rotor. With a huge selection of standard motors—plus our ability to quickly and cost-effectively modify leads, windings, stack lengths and more—you can choose an exact-fit frameless motor that provides simple installation, long life and the highest performance in the most compact space.
Features
Features
- Fully encapsulated stator windings
- 155°C internal winding temperature continuous capability
- PTC thermistor (avalanche-type) overload protection
- Rare-earth neodymium iron boron magnets
- Fail-safe bands over rotor magnets
- RoHS compliant
- UL and CE agency facilitation (Excluding UL for KBM frame sizes 118, 163, and 260)
- Optimizations include rotor hub dimensions, stack length, diameter, mounting features, windings, insulation, connection type and much more
- Optional latching digital Hall effect sensors are pre-aligned and factory-installed with added axial rotor length to achieve proper triggering
Benefits
- Direct load connection eliminates maintenance of gearboxes, belts or pulleys
- Zero backlash and compliance provides more responsive system performance
- Eliminates coupling devices, reducing overall machine size
- Embedded motor enables compact machine design, helps protect your intellectual property
- Huge selection of standard motors and co-engineered modifications for an exact fit, without the time, expense and risk of a fully customized motor
- Modify any standard product’s characteristics – mechanical dimensions, electrical options and connections, thermal and winding optimization for acceleration or deceleration, torque, speed, power, smoothness, and more – to meet your specific needs.
