KBM frameless kit brushless motors

What is direct drive technology?
With direct drive technology a torque motor is coupled directly to the driven load. This provides a very stiff mechanical connection to the load, eliminating problems associated with couplings, belts and gearboxes.

Kollmorgen KBM
KBM™ Series frameless kit brushless motors are designed to be embedded in your machine. The rotor is supported by machine’s own bearings.
A large selection of standard motors are available or alternatively a bespoke solution incorporating your specific modifications can quickly and cost-effectively create a an exact fit motor which will provide the highest performance and longest life in the most compact space.
Designs, which include special winding configurations, tailored mounting features, diameter and stack length dimensional adjustments, or material variations, are all possible.

Simplified Machine Design.
With a Kollmorgen KBM Solution from Micromech, your machine design is simplified. Noisy mechanical transmissions are eliminated as are the performance limitations associated them.

The direct coupling of a torque motor to a load provides improvements to a machine, unachievable with a more compliant mechanical transmission. Furthermore, expensive maintenance is greatly reduced as the need to adjust belts or pulleys or to lubricate gearboxes is eliminated.

Direct drive frameless vs Conventional Motor Systems
Conventional servo systems with mechanical transmissions limit servo performance and reliability. Typically designs consume more space due to use of transmissions, belt / pulley arrangements and couplings. Additionally maintenance is more extensive. This all adds unnecessary machine down time and costs.

Integration Costs

  • Positional inaccuracies from transmission compliance
  • Mounting and alignment of gearbox / belt / bracket
  • Servo tuning difficulties caused by compliance and backlash
  • Pulley installation and tensioning
  • Oversize motor for inertia matching
  • Extra components – clutch, output shaft feedback device
  • Motor / gearbox mounting Bracket
  • Purchasing and BOM
  • Inventory and Inspection
  • Coordinate multiple lead times

Life Cycle Costs

  • Machine maintenance
  • Belt tensioning and replacement
  • Gearbox lubrication and replacement
  • Increasing backlash due to wearing gears
  • Costs to support field failures
  • Unscheduled down time
  • Belt breakageBelt slippage
  • Gearbox failure
  • Reduced throughput due to compliance and settling
