Drive device and method for linear or rotary positioning

A method for non-resonant linear and/or rotary

• moving a first portion of a runner relative to a base using a first actuator group, wherein the first actuator group includes at least one piezoelectric or electrostrictive actuator,
• moving a second portion of the runner relative to the first portion of the runner along a direction of movement using a second actuator group, wherein the second actuator group includes at least one piezoelectric or electrostrictive actuator,
• wherein moving the first portion is performed in the manner of an inertia drive and moving the second portion is performed via a direct or indirect coupling, and
• providing a control signal to the first and second actuator groups, the control signal having at least one inertia drive signal portion comprising sections with different gradients and a semi-static scan signal portion.

A drive device for non-resonant linear and/or rotary positioning of an object, comprising:

• a base;
• a first actuator group having at least one at least one piezoelectric or electrostrictive actuator;
• a second actuator group having at least one piezoelectric or electrostrictive actuator;
• a runner having a first portion and a second portion, the first portion and the second portion being configured to be movable toward one another in at least one direction of movement, wherein the second portion of the runner is the object to be positioned or is coupled to the object to be positioned;
• and
• wherein the first and second actuator groups have a control signal connection configured to receive a control signal having at least one inertia drive signal portion comprising sections with different gradients and a semi-static scan signal portion,
• wherein the first actuator group is configured to move the first portion of the runner relative to the base in response to receiving the control signal,
• wherein the second actuator group is configured to move the second portion relative to the first portion of the runner along the direction of movement in response to receiving the control signal, and
• wherein one of the first or second actuator groups is configured for a movement in the manner of an inertia drive and the other one of the first or second actuator groups is configured for direct or indirect coupling.
