We were asked to study a motor for the compressor driving of the pneumatic suspension system of a high-performance sports car, which had to comply with the following constraints:
The solution and its advantages
A two-pole motor of small dimensions (L=90mm and Ø=63mm) was designed, with a starting torque of 2Nm.
The plastic material used for the brush holder was chosen to withstand high temperatures.
Much attention was paid to the optimisation of the brush holder components; in particular to the guide channels of the brushes that had to withstand the high temperatures reached by these.
