FAQ

Can your motors be driven at something other than their nominal voltage?

Yes. In fact, if you can design your device to run the motor slower (lower than nominal voltage) this is a very good thing. Running at lower voltages (and therefore lower speeds) means less brush bounce and less brush/commutator wear for brush type motors, lower current consumption, and longer motor life. On the other hand, if size restrictions and performance requirements demand additional torque and/or speed, overdriving the motor is possible. You must, however, be willing to sacrifice product lifetime if you overdrive the motor.

How long do your motors and gearheads last?

This varies according to each application. Factors such as operating environment, duty cycle, input power, and how the motor or gear motor is coupled to the load all directly affect product life. Mechanical design factors of the overall mechanism, such as running the motor into hard stops or back-driving the gearheads, affect product lifetime. Generally speaking, brush type motors can run for several thousand hours, when run at nominal conditions. If long lifetime is one of your design criteria, you should consider using brushless motors. These motors are typically limited in their life only by ball bearing wear. If you have detailed questions on this point, it would be best to contact us and call one of our Application Engineers.

What is the maximum continuous current the motor can be exposed to?

This can be calculated from the specifications shown on the motor data sheet. Here's how:

Maximum rotor temperature - Ambient temperature = Allowable temperature rise Allowable temperature rise divided by thermal resistances (add up rotor-to-case and case-to-ambient) = Continuous power that can be dissipated in W.

Set this power = to the current squared x armature resistance. P = I x I x R , Solve for I

There are many more examples of how to determine motor calculations and formulas in our tutorials.

What's the difference between a "servo" motor and a regular motor?

The term "servo" implies that there is a feedback loop which adjusts one or more operating parameters of the motor such as velocity, position, and/or torque. Servomotors are used in closed loop systems where accuracy and repeatability are important. "Regular" motors (without feedback) are run "open loop" where positional accuracy is not an important factor. Learn more about feedback systems and their advantages, here.

Can you run FAULHABER motors and gear-motors on batteries?
Yes. The patented coreless FAULHABER coil - the basis for all modern coreless motors - is designed so that there is no moving iron in the rotor. Only the copper coil turns (around a stationary magnet system). This makes the rotor very low in inertia and able to run at very low current levels, which is optimal for battery operation.
Can you assemble a motor I want with a specific gearhead I want? What about adding cables and terminations?

Yes. We have a Class 100,000 capable clean room that is used for motor and gearhead assembly, cable making, custom circuit board assembly, special soldering operations, and other value-added processes. If you have a special requirement, please contact us.

What factors affect motor noise?
Generally speaking, our motors are designed to be inherently quiet. This is done through material selection, proprietary design techniques, and controlling assembly processes. However, in your application you have additional factors to consider, such as how the motor is mounted in your device, the speed and load at which you operate the motor, and what type of bearing system you use. We can give you some suggestions on how to minimize noise, but ultimately you should test any motor product in your device before you finalize your selection. If you have more specific questions, please contact us.
I notice there are two shaft ends on this motor. Can I get only one?

In most cases, yes. You can select almost all of our motors (both brush, brushless, and stepping) with either a single output shaft or a thru- (double) shaft. Submit a contact form if you want specific information on pricing and product availability.

Can I get feedback devices and other components put on our motor?

Yes, FAULHABER products are designed to accommodate a large variety of supplemental devices. Some of these are spur, planetary or right angle gearboxes, power-off brakes, optical or magnetic encoders. Submit a contact form or call your FAULHABER applications engineer for more detailed information or to review your design.

Can you send me a speed-torque curve for one of your motors?

Yes. We can do that. Please submit a contact form to make the request.
