In the instance of the pictured motor, the customer first gained an understanding of the base-model motors that Pittman offers. The customer then worked closely with the company's design engineers to customize a motor to meet his specific needs. The motor’s housing, flanges, and shaft are built using stainless steel. 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 are 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. Thousands of application-specific solutions have been designed for a broad range of systems such as medical devices, laboratory instrumentation, semiconductor fabrication equipment, robotics, business machines, and numerous others.
