1.2 Drive engineering
1.2.1 Overview
Drive technology is differentiated basically in devices for different “quadrants”: these quad-
rants relate to the direction of speed and torque of the motor with respect to one another.
Speed
Torque
Quadrant 1
Quadrant 2
Quadrant 3
Quadrant 4
The following can be derived from the diagram above:
Quadrant 1: Speed and torque positive, the motor operates in driving mode (outputs power
to the shaft –driving)
Quadrant 2: Speed positive, torque negative, the motor operates in generative mode (ab-
sorbs power from the shaft – braking).
The direction of rotation is the same as in Quadrant 1.
Quadrant 3: Speed and torque negative, the motor operates in driving mode, but in the
opposite direction as in Quadrant 1.
Quadrant 4: Speed negative, torque positive, the motor operates in regenerative mode.
This corresponds to the situation in Quadrant 2, but in the opposite direction of rotation.
