New 60mm Stator design Improved design version now delivers up 110Nmm stall for Ø60mm stator with 6N pretension and 5V supply, see newest motors characteristic here. A calibrated torque-cell with an electrical brake and a load cell to measure pre-tension. This allows us to measure the complete torque/speed curve down to stall at different […]

No, the rotors are preloaded by springs pressing them against the piezo elements. This results in a holding torque whether the power is on or off. The holding torque is about 2-3x the stall torque. Being able to turn motor power off when not rotating can, in some applications, prove to be a very important […]
With no load on the rotor the start/stop time is less than 1 ms. With load on rotors the start and stop time will of course increase.
A PCBMotor has no inherent, mechanically-defined step size. It will rotate with a constant speed of around 1 revolution per sec is requiredond as long as power is applied. To establish and use stepping functionality, a positioning system, see section “Positioning System”.
