Settling Time
Time required for a motion system to cease motion once
the command for motion has ended.
Shaft Radial Load Maximum radial load that can be applied to the end of
the motor shaft at maximum motor speed.
Shaft Runout Deviation from straight line travel.
Slotless Describes the type of laminations used in a motor that
eliminates cogging torque due to magnetic attraction of
the rotor to the stator slots.
Stator
Non-rotating part of a magnetic structure. In a motor, the
stator usually contains the mounting surface, bearings,
and non-rotating windings.
Stiction
Friction encountered when accelerating an object from a
stationary position. Static friction is always greater than
moving friction, and limits the smallest possible
increment of movement.
Straightness of Travel Measure of the side-to-side deviation of a stage as it
travels in a horizontal plane.
Torque Rotary equivalent to force. Equal to the product of the
force perpendicular to the radius of motion and distance
from the center of rotation to the point where the force is
applied.
Torque, Continuous Torque needed to drive a load over a continuous time.
Torque, Peak
Maximum amount of torque a motor can deliver when
the highest allowable peak currents are applied.
Torque, rms Root Mean Square is a mathematical method to
determine a steadfast or average torque for a motor.
Torque, Stall The maximum torque without burning out the motor.
Total Indicated Reading
(TIR) The full indicator reading observed when a dial indicator
is in contact with the part surface during one full
revolution of the part about its axis of rotation.
Tuning In a servo system, the process of optimizing loop gains
(usually PID terms) to achieve the desired response from
a stage or mechanism from an input command.
Unidirectional
Repeatability
See Repeatability
Velocity Command
Motor driver or amplifier configuration where the input
signal is commanding motor velocity. Motors with
analog tachometers are normally driven by this driver
configuration.
