• Position sensor

• Rotor position sensor

Which is come under the explicit position sensor?

• Optical position sensor

• Hall effect position sensor

• Both A and B

• None of the above

At which angle phototransistor is displaced at the end shield cover of the motor?

• 120 deg

• 60 deg

• 180 deg

• 360 deg

How two devices are excited using the light rays falling on the devices?

• Shaft caries circular disc

• Suitable slots are punched in the disc

• None of the above

Which one is practical application device for hall effect position sensor?

• CNC machine

• Washing machine

• Textile machine drive

• Air cooler

Why we go for hall effect position sensor?

• Optical position sensor better effects

• Optical position sensor low efficiency

• Optical position sensor not used in textile because of dust from textile fibers

Which is called as hall effect emf?

• Potential difference between two polarity

• Potential difference between two surface in different polarity

• Different types of switches

• Potential difference between two ends
