general industrial Motor manufacturing CUSTOMER Motor Manufacturer Midwest United States APPLICATION Stator encapsulation. CHALLENGE The company manufactures a wide range of linear, servo and permanent magnet motors, including models used in dirty duty, spark resistant and washdown applications. Motor windings need to be encapsulated to protect copper windings and prevent electrical shorts. Encapsulants also need to be used around motor leads to prevent air and moisture from getting into the windings. Motor windings are densely congured with little room for resin saturation. The challenge was to provide a heated meter/mix system capable of maintaining an elevated resin temperature such that when it was introduced into the motor windings, the lowered viscosity would provide thorough penetration in and around the coil interstices. In preliminary tests conducted at Exact’s facilities, it was determined that a vacuum environment would be required to ensure thorough encapsulation of the windings. Motors were pre-heated to further facilitate saturation. © 2009 Sheepscot Machine Works, LLC. All rights reserved.
