What will happen to the speed of series motor when the supply voltage is reduced?
When the supply voltage to a series motor is reduced, the speed of the motor will also decrease. This is because a series motor's speed is directly related to the applied voltage; as the voltage drops, the current through the motor reduces, leading to a decrease in both torque and speed. Additionally, the reduced voltage results in a lower magnetic field strength, which further contributes to the decrease in speed. Thus, the motor will operate at a lower speed under reduced voltage conditions.
When you change the size of the pulley will it decrease motor speed?
Changing the size of the pulley can affect the motor's speed, depending on the specific configuration of the pulley system. If you increase the size of the driven pulley while keeping the drive pulley size constant, it will decrease the speed of the output shaft. Conversely, if you decrease the size of the driven pulley, it can increase the output speed. Thus, the relationship between pulley size and motor speed is inversely proportional in a basic pulley system.
Causes for a brand new AC capacitor start motor to overheat and shut off?
Two reasons could be that the motor was wired incorrectly or the load that the motor is driving is too heavy for the HP of the motor.
Would the losses decrease if a cooling fan is mounted in the dc motor?
Yes, mounting a cooling fan on a DC motor can help decrease losses by improving heat dissipation. Excessive heat can lead to increased resistance in the motor windings, which contributes to energy losses and can reduce efficiency. By maintaining a lower operating temperature, the motor can perform more efficiently, leading to reduced losses and potentially extending its lifespan.
If the speed of the dc shunt motor falls due to loading what will be the effect?
on adding load on a dc shunt motor, the amount of current and torque will increase. but terminal voltage will decrease
What type of ac motor will operate at a constant speed from no load to full load?
The Synchronous motors will operate at a constant speed from noload to fullload. Even it is classified as an AC motor, we have to fed the motor both AC and DC supplies. That we have to supply DC to the Field (Normally Rotor) and AC to the Armature (Normally Stator).
What happens to to the speed of a motor if i increase or decrease the number of bulbs in a circit?
If you increase the number of bulbs in a circuit, the resistance in the circuit will increase, causing the motor's speed to decrease. If you decrease the number of bulbs, the resistance in the circuit will decrease, causing the motor's speed to increase.
Can you put a minn kota prop on a motor guide motor?
yes, slight modification needed.
Would the losses decrease if a fan is mounted on the motor shaft?
no the lose will increase but motor would not heat up and its wiring will be safe this lose will decrease
Why does a truck or a motor bus have much wider tire?
It is to decrease pressure.
What engines will fit in a Toyota hilux surf?
A Toyota supra motor will fit with slight modifying

If you increase or decrease the frequency what effect on electrical machin?
If you're talking about an electric motor, increasing the frequency will increase the speed of rotation of the motor, and decreasing the frequency will decrease the speed of rotation of the motor. The other way of controlling a motor is to control the current; increasing the current increases speed, decreasing current decreases speed.
What could be the possible reasons why the AC fan motor is not working?
Possible reasons why the AC fan motor is not working could include a faulty motor, a blown fuse, a malfunctioning capacitor, or a problem with the wiring or connections.
What causes your car to jerk during acceleration and the motor to have a slight mist?
try changing plugs and wires
Why noload current in big motors is higher than load current?
In large motors, the no-load current is higher because the motor needs to overcome the friction and windage losses present when running without a load. These losses require more power to overcome, resulting in a higher current draw. When the motor is under a load, the additional power required to turn the load increases the current draw further.
What could be the possible reasons why the furnace blower motor is not working?
Possible reasons why the furnace blower motor is not working could include a faulty motor, a broken belt, a tripped circuit breaker, a malfunctioning thermostat, or a problem with the electrical connections.
