Pittman Motors now offers enhanced customization for its DC motors

February 22, 2013 // By Julien Happich
Pittman Motors now offers customized motor designs for high-end motion control applications, so that the motor meets strict customer specifications for use in harsh environments or demanding applications.

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.
