4-mm linear servomotor aims to replace piezo motors.

Nippon Pulse America introduced its smallest linear servomotor, the 4-mm Linear Shaft Motor. The 4-mm shaft diameter, a small forcer size (10 mm x 10 mm), a total weight of 9 g, and strokes as long as 40 mm make the motor a suitable replacement in piezo type applications, according to the company. The motor is quiet due to the absence of friction since the only mechanical contact section is the linear guide. Its coreless construction totally eliminates cogging. The Linear Shaft Motor's high motor stiffness allows it to be used in high precision positioning applications where a resolution of 0.09 nm is achievable.
