Yaskawa introduces gear motor capabilities for its full Sigma-7 servo line

The Drives & Motion Division of Yaskawa America has released what it says is “a full line of gear motors” based on its Sigma-7 servo motors.

The new line brings “precise Yaskawa servo motion to a wider variety of automation applications than ever before, especially to uses which require high torque at low
output speeds”, says the company.

A new set of gearheads have been designed to pair precisely with every servo motor in the full Sigma-7 range, creating complete gear motor solutions rated from a low of 50W to as high as 7.5 kW. 

Five different gear ratios are available, ranging from 3/1 to 50/1.

Bryan Knight, product manager for the company’s gear motor line, says: “Using a Yaskawa gear motor gives you the best of both worlds.

“You have the opportunity to match the performance characteristics of a Yaskawa servo system to a wider range of mechanical requirements than ever before.

“At the same time, you don’t need to sacrifice the precision and reliability that you’ve come to expect from Yaskawa.”

Yaskawa gearheads are matched with their companion servo motors in mounting conventions, coupling mechanics and output characteristics.

Each is assembled and factory tested at Yaskawa’s facility in Buffalo Grove, Illinois, and includes a full Yaskawa factory warranty.

Yaskawa says the company tradition of manufacturing quality is reflected in each gearhead’s mechanical design, and features:

  • Precision helical gearing with a 40 per cent greater tooth surface area offers notably smoother, quieter and more accurate operation.
  • An enhanced system of bearings, including 45 per cent larger planet bearings for guaranteed alignment, higher stiffness, greater load capacity and longer life.
  • Balanced, concentric shaft couplings to minimize vibration during high speed operation and reduce the inertia of the gear motor system.

The Buffalo Grove facility maintains a complete supply of gearhead and servo motors in stock, assuring quick turnaround for assembly of any gear motor configuration in response to customer need.
