TECO AC Motor High Voltage

Q:It's a 1kW single phase AC pump motor with a 100v supply. This is for a theory question btw. :): use a potentiometer.

Q:what happens when an electric motor is overloaded?: An overloaded AC electric motor will begin to slow down and draw more current than normal. This will cause internal overheating. Most good general purpose motors have an internal high temperature thremostat that will shut them down before any serious damage is done. When the motor has cooled it can be restarted; however, it should not be continued to be operated that way because it will soon fail anyway. The thermostat will likewise stop the motor if the cooling air passages are obstructed and the motor overheats.

Q:We know on undervoltage an ac motor will tend to draw overcurrent. But this should be due to the frequency factor, with frequency acting as a set point for the speed. But is this applicable to dc motor, which doesnt have such set point, and hence in a dc motor current should be proportional to voltage right?: DC or AC doesn't matter. All motors draw high current on starting and it drops as they generate counter EMF. Big motors may have to be started incrementally. Small motors can handle the load but only for seconds. Low voltage is a problem either way. If a motor can't start and run, it can't generate counter EMF and becomes a pure resistance load. Since most motors have low resistance when stalled, they tend to burn. They all do that, AC or DC. If you can't get the motor turning fast enough, it'll burn. It isn't about frequency factor as much as about getting the motor to run fast enough to generate counter EMF. This is a problem at campgrounds where people burn out air conditioning units in their trailers because the voltage is too low after coming through the campground lines. It would be the same if it was DC.

Q:What are the stator and rotor functions of an alternating current motor?: The role of the stator of an alternating current motor is:As part of the magnetic circuit of the motor and embedded stator windings. The stator core is laminated by 0.5mm thick silicon steel sheet, and the two sides of the brick and steel sheet are coated with insulating paint to insulate the sheets and sheets so as to reduce the core loss caused by the rotating magnetic field in the stator core. A plurality of same grooves are punched inside the stator core to be inserted into the stator winding.

Q:after changing the brushes on my wood router with a ac motor it is not working and both wires are live: The brushes are probably tight in their brass holders and not rubbing the armature. You can clean the armature with an eraser and make sure the brushes slide freely against it. Check that the brush springs are free to push the brushes.

Q:How to connect the AC motor?: Triangle: above line three root three terminals connected with three-phase power supply, the three terminals should pay attention to the connection, the end of U phase U2 wire and V head end V1 shorted end of V phase V2 wire and W head end W1 shorted end of W phase W2 wire U and U1 head end short circuit.

Q:i have the following specifications for an ac motor with a built in constant torque drive.10:1 constant torque3600rpm250HPWhat Does the ratio mean?: Check okorder /

Q:i have an induction motor that produces an AC. i connected it to a full wave rectifier that i made and connected that to a DC motor but it didn't work. and the DC voltage generated by the induction motor alone through the rectifiers is about 60V, but it drops close to 0 once it's connected to the DC motor. is it possible to power 1 motor with the power produced by another motor? is there something, like a capacitor, that i need to connect between the rectifier and the dc motor for this to work?: i'm hoping you do not concepts yet i am going to rephrase the question as I see it. If i take advantage of a 4.5 volt direct modern-day motor like an instantaneous modern-day generator, how a lot capacity will it generate ? At a wager with out understanding how briskly you spin the motor/generator and adequate filtering, the load you shop on with to the generator, how briskly you turn the shaft, someplace about 3 to 4 volts at about 100-300mA. you incredibly desire to construct a try rig with the motor appearing as a generator and create a circuit with a 10,000uF 15 volt electrolytic capacitor properly polarised in the course of the output terminals of the motor/generator and then position different resistances in sequence with motor/generator and use a voltmeter to make sure what outputs you are able to anticipate for what rpm you spin the motor/generator at. you would discover out of your finding out a large fluctuation in output and hence some type of regulation circuit will be needed.

Q:i conducted experiment by taking two electric motors from rc toys and connected them by gears.1.5v is supplied to a motor and other motor also rotates due to gear arrangement.we also know that electricity is generated in second motor.i want to know electricity generated is ac or dc current.: The current generated is ac current.

Q:In A.C motor we have all three phase currents equally or separately supplied for each phase. In D.C motor only one current. The load can appear in the equation in any form.: You can start with the equation that input electrical power is mechanical power delivered to the load by the motor shaft plus losses. For DC, Power (Watts) = Voltage (Volts) X Current (Amperes). For three phase AC, Power (Watts) = RMS Line Voltage (Volts) X RMS Line Current (Amperes) X Square Root of 3 (1.732) X Power Factor (Cos of phase difference between voltage and current). For mechanical power, Power (Watts) = Torque (Newton – Meters) X Rotational Speed (radians per second). Therefore: For a DC motor, Input Current = (Torque X Speed + Losses) / Input Voltage. For a 3-Phase AC motor, Input Current = (Torque X Speed + Losses) / (Input Voltage X 1.732 X pf) The losses include both electrical losses and mechanical losses that are proportional to voltage, current, frequency (for AC), and speed. Speed depends on the speed vs. torque characteristics of the driven load and the speed vs. torque characteristics of the motor. At steady state, the motor operates at the intersection of the motor speed vs. torque curve and the load speed vs. torque curve. The DC motor speed vs. torque curve depends on the machine design and the applied voltage. The AC motor speed vs. torque curve depends on the machine design and the applied frequency and voltage. It is also important to note that the power factor of an AC motor is not constant. It varies with load.
