The power heart of every motor,precision-built here
Steel sourcing, custom shaft cutting, and precise rotor press-fitting — a one-stop OEM service delivering the most stable, reliable rotor assemblies.
About us
We specialize in the precision machining and assembly of motor core components, offering an end-to-end OEM service — from premium steel sourcing and custom shaft cutting to precise rotor press-fitting — delivering the most stable and reliable "power heart" to leading motor brands.
Core process and services
We understand that the rotor assembly is the key to motor performance. That is why we rigorously control every step of the process, providing the following core services:
Premium material sourcing
We carefully select high-quality domestic steels, including 304 and 403 stainless steel and medium-carbon steel, along with motor rotors, ensuring the final product delivers excellent physical strength and durability.
Custom precision machining (OEM)
Based on customer-supplied drawings, we perform high-precision turning, milling, and grinding to craft motor shafts that precisely meet a wide range of head and horsepower requirements.
Rotor press-fitting and integration
Using professional equipment, we precisely press the finished shaft into the rotor, ensuring exceptional concentricity and dynamic balance.
Precise assembly delivery
We deliver high-quality rotor-assembly semi-finished products, so downstream motor manufacturers can feed them directly into their final assembly line, greatly improving production efficiency.
Why choose STARVEX
For motor brands and assembly plants, our OEM services bring the following concrete advantages:
Streamlined production
We free customers from the burden of building costly in-house shaft-machining lines and from managing complex metal-waste systems.
Higher assembly yield
By focusing on a single critical component, we keep the shaft-to-rotor fit tolerance within the strictest range, significantly reducing vibration and noise during high-speed operation.
Local vertical integration
From domestic material sourcing to machining and assembly under one roof, we provide a stable-quality, on-time source of core components.
