The smallest translation you can make.
Of the possible degrees of freedom of the mount or stage, the number that are motorized.
Our specifications are guaranteed only in this temperature range. If your application demands high- or low-temperature operation, call us for more information.
For linear positioners, this is the Picomotor actuator’s translation rate with no load; for the rotary, it is the rotation rate. The speed of the device is directly related to the rate at which pulses are applied, the minimum angular resolution, and, in the case of linear positioners, the screw thread pitch. We calculated speed assuming a pulse rate of 1 kHz, which all our drivers can produce.
The typical translation caused by applying a single voltage pulse to the Picomotor actuator. Since the Picomotor actuator relies on friction to turn a screw, the step size will vary slightly from pulse to pulse. (See “Angular Resolution” for more information.)
The torque that the Picomotor actuator can exert before stalling. Since the Picomotor actuator depends on friction to move, overloads can prevent the actuator from moving at all. As maximum torque load is approached, typical step size decreases.
The difference in angular position between the first flip and the 10,000th flip.
A measure of the degree to which a given displacement matches a standard.
A measure of how well the device returns to a set position over many attempts and when approached from either direction.
