Customized Motors for High-End Motion Control Applications
Highly customized DC motors can be designed to meet strict user specifications for use in harsh environments or demanding applications. The motor pictured here uses stainless steel for the housing, flanges, and shaft. The motor’s inside is protected from debris and moisture using a combination of seals, including a dynamic labyrinth seal on the front mounting surface and o-rings between the flanges and housing. The customized brushless motor design provides a high level of sealing against particulates and moisture as well as splashes from the corrosive environment. A dynamic labyrinth seal provides protection from dust contamination, while allowing the motor to operate at high shaft speeds. A stainless steel cable gland and silicon cable sleeve is used for enhanced ingress protection. The 4-pole brushless motor also was optimized for 24 hour/day operation at speeds ranging from 500 RPM up to 15,000 RPM. It is constructed using high-grade, low-loss lamination steel to increase efficiency at high speeds and skewed rare-earth permanent magnets to minimize cogging at low speeds. The motor is electronically commutated using integrated hall-effect devices.
