26 Frame PMDC Motor Available hp from 1/53 to 1/9 hp, with speeds from 4246 to 1800 rpm. Available in 12, 24, and 90 volt imput power. 90 volt motors are rated to run continuously using SCR type controls at 1.4 form factor. Brushes are replaceable for all units. Units are available from stock nationwide. Custom windings, shafts, and assemblies are available in OEM quantities. Precision machined shafts can be customized to your design needs. External access to extended life brushes eases inspection and maintenance. Constant pressure stainless steel springs and large, oversize brushes maximize brush life. Optimum commutation is developed even with the most demanding applications! Diamond turned commutator with fusion bonded tang welding for maximum reliability and long life. 36 inch, three conductor cordset standard on all PMDC motors. Optional junction boxes available. Baked on epoxy powder coat paint finish, high gloss black, for durability and maximum heat transfer. UL component recognized, and UL approved Class F insulation system. High temperature magnet wire coupled with superior trickle varnish system. Precision machined shafts can be customized to your design needs. Shielded ball bearings (permanently lubricated, electric motor grade) maximize operating life and overhung load capability. Preload spring minimizes endplay, reducing vibration and noise. Four 0.125" x 0.40" deep cored holes on a 1.5" diameter circle for self tapping screws. Drilled and tapped (10-32) armature shaft for encoder mounting or available shaft extension kit. Drilled and tapped (1/4"-20 UNC-2B x 0.44" deep) base mount for ease in mounting. High energy ceramic magnets for high starting torque and reduced operating temperatures. Injection molded Rynite® insulator provides superior resistance to electrical failure.
