Analysis of test results indicated a consistent difference
in torque ripple between high and low displacement
motor sharing the same cam (Typically 2% for low
displacement and 5% for high displacement)
Investigation has revealed that the MCR cam designs
are optimised for low displacement rollers and when
using the larger roller diameter of high displacement
rotary group, the torque ripple increases
Work is ongoing to optimise a separate cam for high and
low displacement motors with an expected motor
efficiency increase of 5% for high displacements
Starting Efficiency Improvements: Optimised Cam
