The angular position of the rotor shaft in synchronous electric motors is measured by the high-speed rotor position sensor.
In electric and hybrid vehicles, the e-machine torque control needs to be driven by the sensor signal. The motor inverter receives an analogue 0-360° sine and cosine output signal from this standalone sensor, which is based on very precise TMR technology.
The durable, overmolded PCB-free design of this small and slender sensing solution allows it to be fitted at the rotor shaft’s end with ease.
It combines multiple tasks. The redundant sine and cosine output signals, information from the stator temperature sensor, and a grounding connection can all be routed through the integrated outside connector with supplies.
The Global Automotive Rotor position sensor market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
Wells Engineering introduced Rotary Position Sensors for Applications in Traction Motors for Electric Vehicles.
The Rotary Position Sensors from Wells Engineered Products employ hall-effect sensors with two-axis sinusoidal magnetization to give superior accuracy in a more compact and lightweight package than standard transformer resolvers and variable reluctance resolvers.
Accurate rotor position monitoring is crucial since EV performance depends on controllability, performance, and smooth torque.
Their Rotary Position Sensors provide EV traction motor designers chances for improved designs with higher performance at a reduced cost because they are more compact than a standard VR resolver and connect easily into new or current motor designs, including hub motors.
Wells’ Rotary Position Sensors offer higher accuracy in a smaller, lighter size and a semi-circular form for applications requiring a compact footprint, making them adaptable to different mounting methods and locations.
They feature built-in redundancy, are entirely replaceable, and are simple to tune to any position. Wells Engineered Products can fill small, medium, and large-volume orders affordably since its sensors are produced on highly automated machinery.
