The op-amp is rigged as a voltage sensitive switch. In the circuit demonstrated below, as soon as the output of the tacho-generator is lower than the preset reference voltage the switching transistor be turned ON and 100 % power will be provided to the motor. Switching action of the op a...
UVLO response conditions VVCC Device Response <1.65 V UVLO >1.65 V Normal Operation IPROPI Not available Available for VVM > 1.65 V 7.3.7.4 Overvoltage Protection (OVP) When the motor is driven by external force, it acts as a generator and pumps back current to the supply voltage rail. ...
A resistor and an unknown device are connected in series with an AC generator as shown in the diagram below. The current lags behind the voltage of the generator by 51°. (a) If the total impedance of the circuit is 188 Ω, what is the value of the Question 1 a) A 5.0 ...
How to convert DC power to AC power with a formula AB is a potentiometer wire of resistance 1 ohm being used to measure a small voltage of 2/3 mV. The cell has an emf of 2 V and negligible internal resistance. For the balance point to be 2/3 of the way along the slidewire, as...
1: A (DC) motor is a generator as well. Turn the shaft and you can measure a voltage from the motor terminals. When the motor is turned at the nominal speed, it will in principle produce the nominal voltage. If you now connect said nominal voltage to the motor terminals, _no_ curren...
