Printed armature motors, also known as pancake or servo disc motors, bring a host of features as well as compact dimensions to a number of applications. Traditionally, they have also brought along a high price tag, which has kept the technology from widespread adoption. Printed Motor Works Ltd hopes to change that with the introduction of its GSR range of pancake motors.
For the first time, says the company, pancake motors can be considered a realistic alternative to conventional dc and universal electric motors for a number of applications, including medical equipment. GSR motors offer rapid response, long brush life and low EMC emissions—features that have always been associated with pancake motors—but at a more attractive price point. Moreover, these are reportedly the only motors in the world with zero torque ripple.
The company adds that GSR motors are easier to install, quieter, more efficient and even flatter than previous generations of pancake motors. The 70-W models can be as thin as 19 mm.
Data for the GSR range can be accessed at the company’s website. Performance validating samples are available immediately; full production is planned to start in the second quarter of 2010.
