Thiết bị kiểm tra cân chỉnh động cơ Octava PoleStar
The adjustable-height PoleStar rotates the motor shaft at constant speeds (ranging from 0 to 1,000 RPM) for faster, hands-free operation and to measure the Back Electro-motive Force (BEMF).
Included: Make quick connections with the 6 pc. L-JAW HUB Kit or 1 pc. 3-JAW CHUCK .
What is Back Electro-motive Force (BEMF)?
Back EMF is the voltage generated when a permanent magnet motor is rotated. This "kick-back" or counterforce is called Back Electro-motive Force or Back-EMF (BEMF).
Why Measure the Back EMF at 1000 RPM?
Measure the Back Electro-motive Force to check the rotor's magnetic strength and winding condition.
Test Procedures:
- Connect the motor to PoleStar with a coupling
- Make sure it is level so that the motor is not damaged
- Set PoleStar to 1000 RPMs
- While the motor is running, measure UVW phase-to-phase
