Analyser provides in-depth motor data
Servomotor analyser measures 15 motor parameters, including torque constant, motor constant, rotor friction, moment of inertia, as well as winding resistance and inductance.
Motor testing systems have been around for decades But aside from the addition of fancy graphical user interfaces, these systems remain largely unchanged

It's the scales that count
A new range of industrial counting scales suits the needs of a variety of industries where parts counting is essential for inventory control, packaging checks and component handling.
Alarming performance from weighing scales
Adam Equipment has introduced a new range of industrial weighing scales to suit the needs of a wide variety of industries from building supplies to electronics manufacturing.
Many systems are still limited to a handful of very basic tests such as winding resistance and hipot leakage.
These are very useful tests, but for mechanical design engineers who are validating new motor designs, control system engineers who need to produce accurate models of a servomotor, or the failure analysis technician who need to identify motor problems - a more comprehensive test is needed.
The recent introduction of the 3320A servomotor analyser by Avelly fills this void in the motor test world.
With the ability to measure 15 motor parameters such as torque constant, motor constant, rotor friction, moment of inertia, as well as winding resistance and inductance - the analyser provides much more information than the standard pass/fail.
The unit can also generate a number of plots including a family of torque versus speed plots.
Supported motor types include small to medium sized brush and brushless DC permanent magnet motors.
The motor analyser is a fully integrated unit which can sit on a benchtop or in a 19in rack.
Other functions of the Avelly analyser include the ability to test encoders and commutation sensors (eg Hall effect sensors).
For example, the 3320A can produce a plot showing how well a commutation sensor is aligned to the motor's back-EMF and report the exact angle of misalignment.
This is an important feature since malfunctioning or misaligned sensors can reduce torque output and cause excessive motor vibration, noise and loss of efficiency.
Without specialised test equipment, conducting an in-depth analysis of a servomotor is a time consuming task.
Avelly's 3320A conducts a full suite of tests - a complete analysis of a servomotor - in a matter of minutes.
