Frequently Asked Questions
Motor FAQ
Q. What frames and sizes of motors does Stainless Motors offer?
A. We offer stainless steel motors in sizes from 1/4HP to 50HP in TEFC (fan cooled) designs, and up to 700HP in water cooled designs. Motors are available with speeds of 3500, 1750, 1160, and 850 RPM.
Q. Do you offer metric frame motors?
A. We offer IEC (metric) frame motors in sizes from 0.18kW to 22kW in any Hz/Voltage rating.
Q. Where are these motors made?
A. All of our products are engineered, manufactured, and supported at our plant in Rio Rancho (Albuquerque), NM, USA.
Q. Why can’t I find prices on the website?
A. Our highly trained sales staff will provide a price based on the specific requirements of your application.
Q. Do you offer custom motors?
A. We can provide custom feet, shaft, cable entry, volts/Hz, and other features to suit your special requirements.
Q. Do you offer DC motors?
A. No.
Q. Do your motors have encapsulated windings?
A. No. Other manufacturers encapsulate their windings to protect them from water. However, if water is inside the motor the shaft seal has been compromised and the bearings are going to fail. Our sealing technology is so advanced that we keep water out of the motor, thereby eliminating the need for encapsulation.
Q. What about condensation inside the motor?
A. Condensation will only occur if there is exchange of air allowing moisture to enter the motor. Our design prevents air exchange from occurring.
Q. What is your warranty period?
A. All of our products are covered by our limited 1-year warranty.
Q. If your design is superior, why don’t you offer a longer warranty period?
A. If one of our motors fails, we want to be involved in evaluating the application so we can recommend a solution. Simply replacing the motor will not solve the problem since there are unknown factors that contributed to the failure.
Q. Do you offer explosion proof motors?
A. We offer inverter duty XP motors for Class 1 and Class 2 hazardous locations in sizes up to 2HP at 1750 RPM and 3HP at 3500 RPM. Larger sizes will be available in late 2011.
Q. Are your motors available with brakes?
A. We can install spring loaded electro mechanical brakes with a manual release on our motors. The brake is housed in a stainless enclosure.
Q. Do you have a solution to a motor that mounts shaft-up allowing water to get inside past the shaft seal causing repeated failure?
A. We have special designs for a variety of mounting orientations, including shaft-up installation. Our shaft-up design includes a custom endbell and shaft umbrella that sheds the water right off the motor so it never contacts the seal.
Q. Can your motors operate in a freezer?
A. Our Freezer Duty motors include custom features for operation at sub-freezing temperatures.
Q. Are your motors submersible?
A. We have Submersion Duty (IP68) motors designed to operate under water.
Q. Can your motors be serviced at any motor repair facility?
A. Due to the unique construction of our motors, we recommend they be returned to us if they ever need service.
Q. Do you have motors for high ambient temperature applications?
A. We offer motors with Class H insulation for high temperature installations, as well as custom cooling options.
Q. Do you offer motors in aluminum or painted steel?
A. No, only in stainless steel.
Q. What grade of stainless are your motors made of?
A. Our standard grade is Type 304 for all outer surfaces, and 17-4 H1150 for the shaft. We can also provide motors made of all Type 316 stainless.
Q. Are your motors inverter duty?
A. All of our motors are inverter duty.
Q. What is your freight policy?
A. All products ship FOB our plant in Rio Rancho, NM .
Q. What is the Service Factor of your motors?
A. Most of our motors have a 1.15 S.F.
Q. Do your motors meet the latest efficiency standards?
A. All of our motors meet the latest efficiency criteria of EISA 2007 that took effect in December of 2010. IEC (metric) frame motors meet the requirements of IE3 efficiency class.
