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.
Product available worldwide
Increase Uptime
Reduce the complexity of your machine's design. Directly driving your load by removing failure prone transmissions will decrease the likelihood of costly failures and reduce the need for expensive, preventive maintenance. The end result is a reduced total cost of ownership in your machine.
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
- 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.
