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.
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.
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.
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.
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.
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.
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.
