Kistler has launched a modular test
stand system designed for testing
electric motors and gearing. The
stands can incorporate a wide range
of torque and speed sensors with
manual or computer control, and can
be equipped with an integrated power
analyser with up to 12 voltage and 12
current measurement channels to
provide separate efficiency specifi –
cation for the motor and converter.

The load on the motor under test
is provided by an active brake
working in four quadrants. Sensors
to measure torque from 0.01 to
25,000Nm, power from 2W to
500kW and speed up to 120,000rpm
may be combined with a wide range
of mechanical components, power
analyser for data logging, signal
conditioning and data interface.
