Time required for a motion system to cease motion once
the command for motion has ended.
Maximum radial load that can be applied to the end of
the motor shaft at maximum motor speed.
Deviation from straight line travel.
Describes the type of laminations used in a motor that
eliminates cogging torque due to magnetic attraction of
the rotor to the stator slots.
Non-rotating part of a magnetic structure. In a motor, the
stator usually contains the mounting surface, bearings,
and non-rotating windings.
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.
Measure of the side-to-side deviation of a stage as it
travels in a horizontal plane.
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 needed to drive a load over a continuous time.
Maximum amount of torque a motor can deliver when
the highest allowable peak currents are applied.
Root Mean Square is a mathematical method to
determine a steadfast or average torque for a motor.
The maximum torque without burning out the motor.
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.
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.
See Repeatability
Motor driver or amplifier configuration where the input
signal is commanding motor velocity. Motors with
analog tachometers are normally driven by this driver
configuration.
