The drive motor (2) and clamping bracket (3) are bolted
together through a rigid plate. The flywheel (1) is at-
tached directly to the shaft taper on the drive motor
(2). This drive unit is mounted in bearings on anti-vi-
bration mountings (4) in the test-bench frame (5). The
series 8 test benches feature a stepless, variable-speed
electronic drive. In technical terms, a field-controlled,
4-quadrant frequency converter with a vectorial control
loop is combined with a three-phase a.c. motor. This
drive motor (2) was designed to be used in conjunction
with injection-pump testing.
�.5.2 Control cabinet, control unit
All the electrical components and control elements re-
quired for operation are housed in the control cabinet.
