Check rotator runout for EV motor

星期二, 四月 18, 2023

For Electric Vehicle motors, two key components are the rotator, and the stator housing.  The rotator spins inside the stator using a magnetic field.  The rotator and “rotator blades” must meet a tight specification so that it spins freely inside the housing and performs at full efficiency.

Solartron’s precise, yet robust gauging probes have been used them to check the runout of the rotator for an electric motor, as well as the height and runout of the rotator blades.
The reasons that Solartron probes were chosen include:

High Accuracy, even with a sideload: Solartron Digital probes have stated accuracy of up to 0.05% of reading. This accuracy is maintained even when the probe incurs a sideload due to TIR or a moving surface.

High Resolution: Solartron probes provide a resolution as low as 0.01 microns, meaning even the slightest variation for TIR measurements can be recorded.

Robust, long lasting build: All Solartron probes are crafted in a UK factory. The designs easily last over 100 million cycles with no sideload and are tested to over 10 million cycles in an abusive “sidecam” test with no loss of repeatability.

Compact Size: Solartron’s gauging sensors are much more compact than competing sensors, such as Linear Encoders or other glass scales. The 2mm range DZ probe is just 29 mm in length.

Multiple signal outputs: Solartron provides a full array of outputs, which include analog DC & 4-20mA, as well as digital outputs to PC and PLCs. Partial and fully automated software packages are also available.


Solartron’s measuring solutions can be used in many measurements in EV industry.
