Piezo Electronics

Piezo actuators and positioning systems require unique drive and control electronics. DSM offers off-the-shelf electronics and custom circuit design services for piezo-based applications.

Motor Driver MD-90

The MD-90 is a 2-channel linear amplifier for operating the I-20 piezo motor. This original equipment manufacturer (OEM) unit can be used in two primary ways as a: 1.) 2-channel piezo motor driver complete with quadrature encoder feedback and 2.) 2-channel piezo device amplifier with analog feedback for both closed and open loop operation.
