PoleStar Back EMF Motor Test Stand
Height adjustable Back EMF (BEMF) motor test stand with PID speed control displays the RPM and rotates the motor shaft at constant speeds for faster, hands-free operation.
Included: Make quick connections with the Lovejoy coupler kit.
What is Back Electro-motive Force?
BEMF is the voltage generated during the operation of a rotating machine (a generator or a motor). When voltage (an electro-motive force) is applied to a motor's armature, it begins to rotate, and the magnetic field generates an amount of electrical resistance.
This "kick-back" or counterforce is called Back Electro-motive Force or Back-EMF ( BEMF ).
