This is a pre-assembled DC Motor designed for students to learn about electromagnetic forces. The open structure resembles the diagram found in many textbooks. The polarity of the magnets can be reversed to change the direction of the rotation. The motor can also be used with a rheostat to observe the change of speed with the change of current.
Complete with internal driver. Current: 30mA Sound output: 85db @ 10cm Frequency: 2KHz.
