Spin Testing for High-Speed Electric Motors

The growing prevalence of high-speed electric motors in aerospace, automotive and industrial equipment makes efficiently testing these devices more important than ever.

Many nascent high-performance motors are designed to operate at much faster speeds than traditional units, which means they require superior robustness and durability. Some of the biggest concerns regarding electric motor spin testing revolve around designing and validating the structural integrity, balancing strategy, and durability of the rotor. Successfully accounting for these traits help electric motors operate effectively in applications ranging from electric vehicles, drones, UAMs (Urban Air Mobility) and hybrid drive/propulsion systems.

Drawing from 40+ years of experience in advanced spin testing, Test Devices provides innovative solutions to challenging problems in engineering, testing, and manufacturing spin processes. We believe we can help accelerate your high-speed motor development by providing you with the most relevant test data.

    Rotor Growth and Profile Mapping

    TDI offers two types of rotor growth measurements:

    Rotor Growth Measurement

    When performing this service, we measure the average expansion of a rotor under a CF load (Figure 1), which captures the bulk material behavior of the rotor. This process allows us to validate (or tune) the material model using rotor growth data.

    Rotor Growth Profile Mapping

    In this service, we measure the detailed 360 ̊ contour of the rotor as it deforms under spinning conditions (Figure 2). The technique captures the detail of localized change in the rotor growth, which helps us understand the effect of the internal structure on its deformation shape. For example, the data from this test helps us understand the impact of rotor structural design for the embedded magnet (or windings) on its surface deformation, which could affect the air gap requirement of an electric motor.
