Leads: The wires exiting out of the motor terminal box used to connect the motor and/or accessories to the power supply.

Line Voltage: Voltage supplied by the power company or voltage supplied as input to the device.

Linear Acceleration/Deceleration (LAD): A Circuit that controls the rate at which the motor is allowed to accelerate to a set speed or decelerate to zero speed. On most drives, this circuit is adjustable and can be set to accommodate a particular application.

Linearity: The measure of the maximum deviation between the actual speed and the set speed, expressed as a percentage of set speed.

Locked-Rotor Current: The steady-state current taken from the line with the rotor locked and with rated voltage (and rated frequency in the case of alternating-current motors) applied to the motor.

Locked-Rotor Torque: (Static Torque) The locked-rotor torque of a motor is the minimum torque which it will develop at rest for all angular positions of the rotor, with rated voltage applied at rated frequency.

Long Shaft Motor: NEMA standard MG-1 defines shaft length as the dimension AH, or the distance from the face, flange or base of the machine to the end of the shaft. In a standard type "T" frame the NEMA standard shaft extension (long shaft) is supplied. It is normally used where overhung loads from pulleys, shieves and sprockets are encountered.
