Design of an Industry-standard Electric Motor Test Bench

Testing newly developed electric motors is a major step in the process of motor design, validation, and standardization. This process typically involves determining the motor's core parameters, such as the torque, speed, thermal response, and power density. This can be said to be part of an overall motor evaluation equipment framework.

In this publication, I am going to present an industry-standard electric motor test bench that I developed for experimentally validating the coreless magnetic resonance motor. The research work was published in the IEEE Transactions on Industrial Electronics titled  “Design and Experimental Analysis of a Novel Coreless Resonant Motor”.

The test bench itself is a rigid mechanical structure that can withstand high machine speed vibration, electromagnetic load current variation associated vibrations. The rigidity of the mechanical structure helps to hold all mechanical parts in place, limiting vibrations during the different motor speeds and torques. 

The disassembled 3D CAD Model of the Test Bench Structure is shown below. The structure is modeled with SolidWorks. All the mechanical parts were procured from the well-known mechanical parts distributor Misumi.
