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

Kollmorgen leads the way with hygienic design for use in meat processing

Hygiene is no longer the sole driver of innovation in the food processing industry. All of the requirements in terms of cleanliness and food safety in machine design relate primarily to productivity, modularity, durability, and availability. Full of technical features that Kollmorgen has successfully combined in the stainless steel servo motors from the AKMH series.

Kollmorgen - AKMH SeriesHygiene is expected—the only question is how intelligently this requirement is taken into account in machinery and the production facilities. Kollmorgen has succeeded in combining a clean exterior with high drive performance, easy cleaning, and above all, high availability with the stainless steel servo motors from the AKMH series. The internal structural design effectively removes heat losses outwards. Stainless steel has low thermal conductivity, and so motors made of this material normally have problems in this area. The improved heat removal capacity increases drive performance directly in practical usage, as the synchronous servo motors deliver more output for the same design size.

Heat and cold with rapid changes in temperature, plus plenty of water. This interaction creates a further, more serious effect of condensation in a motor’s interior particularly in the meat processing industry. This is caused by the temperature-related constant pressure equalization, since the volume of the gases expands with heat and contracts with cold. Kollmorgen has found a way around this law of physics with a ventilation function via the motor cable. This ensures that the pressure equalization does not take place locally with the humid air of the meat processing operation, instead uses the preferred temperature of the control cabinet’s protected atmosphere.

The hygienic motors can easily be adapted to allow installation into existing automation structures, for example to suit an existing feedback format. This means the motor can be selected independently of the existing frequency convertor, which is also a real asset when it comes to updating existing systems.
