Spinea launches new servo actuator for precision motion

June 2, 2017 by Sam Francis

Spinea has launched its new DS 095 DriveSpin servo actuator motor for precision control.

Recently announced by Spinea and available in the UK from Heason Technology, the DriveSpin DS 095 series integrates the industry leading TwinSpin high-load capacity trochoidal gear unit and a powerful AC servomotor with servo feedback for a cutting-edge rotary actuator solution for precision motion applications.

The inline (non-hollowshaft) design of the DS 095 fulfils the gap between the DS 70 and DS 100 models to provide a rated torque of up to 85 Nm and maximum lost motion and hysteresis values of less than one arc-min. [Read more…] about Spinea launches new servo actuator for precision motion

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

May 27, 2017 by Sam Francis

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. [Read more…] about Yaskawa introduces gear motor capabilities for its full Sigma-7 servo line

Nord Drivesystems shows modular industrial gear units in additional sizes

May 25, 2017 by Sam Francis

Nord Drivesystems has presented two new gearboxes for nominal torques of 15 and 20 kNm.

The company says its new industrial gear units greatly increase the possibilities for configuring application-specific drives in the load range up to 20,000 Nm, for example with a dual gear setup and swing base.

With these latest additions to the line-up, the series now comprises 11 gearbox sizes that deliver output torques up to 250 kNm. [Read more…] about Nord Drivesystems shows modular industrial gear units in additional sizes

Redesigning the gear: A closer look at Harmonic Drive’s new WavePlus technology

February 19, 2017 by Sam Francis

Graham Mackrell, managing director of precision gearing expert Harmonic Drive UK, explains WavePlus technology, an innovative development in strain wave gearing

Sometimes, you only need one small innovation to make something revolutionary.

Sliced bread, for example, simply took a stroke of inspiration for Otto Rohwedder to combine automatic bread wrapping equipment with cutting functionality.

The strain wave gear has been the pinnacle of precision gearing since the technology was first developed in 1957 by renowned inventor and founder of Harmonic Drive, Walton Musser.

Consisting of just three crucial components – the wave generator, flexspline and the circular spline – and ensuring zero backlash as well as a high gear reduction ratio, strain wave gears have long been the standard for critical applications.
