Does NMB carry outer rotor and inner rotor motors? What are the advantages between the two?
NMB carries to sizes of outer rotor motors, 20mm and 25mm. The advantage of an outer rotor motor is torque. These smaller packages can produce more torque than there equivalent inner rotor size motors. This is accomplished by the larger moment arm of the rotating outer rotor magnet. One disadvantage is speed capability. If high speeds exceeding 6,000 RPM are required, it is recommended you utilize an inner rotor construction motor.
