M-674 PILine Rod Drive
Warsash Scientific has introduced PI’s M-674 PILine Rod Drive, a piezo linear motor with compact form factor, low-profile, high velocities and good position resolution.
The M-674 PILine Rod Drive features a patented, ceramic, ultrasonic drive and can easily be used to replace classical drive elements like motor/leadscrew assemblies or magnetic linear drives.
M-674 PILine Rod Drive consists of a rod-shaped runner moved and guided by patented PILine piezo linear motors pressed against it from two opposing sides.
Depending on the application design, either the runner or the motor housing can be coupled to the moving part.
The highly compact, integrated piezomotors in the M-674 can provide high accelerations, velocities of up to 450 mm/s and generated forces up to 7 N.
Because ceramic motors provide high holding forces at rest, the M-674 with its integrated piezomotor offers good position stability without the heat generation characteristic of conventional linear motors.
Standard versions of the M-674 are available with travel ranges of 50, 100 and 150 mm, and find application in the fields such as metrology, micromanipulation and biotechnology.
Special operating and holding force requirements can be fulfilled by varying the characteristics of the piezo motors used.
