MTP Open Loop Actuator

Drawings and Documents

The MTP is an internally preloaded piezoelectric open loop translation device capable of moving up to 105μm with very high resolution.

The actuators offer a very stiff design that is capable of generating blocking forces as high as 1000N (MTP-15). This characteristic enables the actuator to drive demanding loads of up to a maximum 10kg (MTP-15) in the Z-axis. Driving the MTP actuator over nominal range simply requires a 0V to 120VDC HV amplifier. However, if required, it is possible to achieve additional range by using a -30V to 150VDC capable HV amplifier.

If a small form factor and closed loop performance is required the MTP can be used in conjunction with a Queensgate’s position measurement system. This provides capacitive position sensing for sub-nanometre precision with the benefit of independent sensor placement from the actuator. This allows the freedom to mount the sensor plates at any convenient point on the host fixture.
