Only 3mm in diameter and 12mm in overall length the new Physik Instrumente P-915K094 miniature rotary piezo motor is capable of speeds of up to 1000rev/min with a torque of 0.4mNm.
Only 3mm in diameter and 12mm in overall length the new Physik Instrumente P-915K094 miniature rotary piezo motor is capable of speeds of up to 1000rev/min with a torque of 0.4mNm.
It offers a high static holding force even when powered off and, being piezo driven, it does not create or require magnetic fields nor is it influenced by them.
The new micromotor is one of a range of PI piezo motors available with a series of PWM motor controllers.
Rotary piezo motors are also used in a new range of high resolution micrometers offering 10, 25 or 50mm of travel with 0.5um step resolution.
The PI M-277 series have a nonrotating tip eliminating torque-induced platform tilt, sinusoidal motion errors, tip-angle dependent wobble and contact wear.
In addition to manual movement the new micrometers offer handheld control pad for easy high-resolution tip control.
