How many AMPs does a 7.5HP motor need?
depending on 1phase or 3phase voltage motor , the amphere requirement is found outfor 3phase AC motor use this formula: (HP x 746)/(1.73 x E x Eff x PF)for 1phase AC motor : (HP x 746) / (E x Eff x PF)
4 Plugging of DC motor is normally executed by?
In case of 1phase the reverse torque is obtained by reversing the current either in armature or field
Can a 600 volt 3phase electric motor run on 1phase?
Yes it can run when single phasing in a delta configuration but the motor will not start from a dead stop. There will be quite a bit of degradation in its operation from its nameplate data.
How does a frequency inverter work?
A frequency converter converts alternating current of one frequency to alternating current of another frequency. Generally it's used for controlling the ac motor speed by changing the supply frequency.
An example of a stepper motor miniature dc motor and an ac motor?
stepper motor :- motor used for controlling direction of movement of robotic arm dc motor :- motor used in cellphones as vibrators ac motor :- motor used in textile machinery

Can you run a small drill press 3 plase on 1phase?
Not without another 3-phase motor, a "pony motor," or maybe some crazy expensive solid state "wizard black box." Here is the cheaper way: You would need an appropriately rated transformer to bring your single-phase supply voltage up to the voltage required by your 3-phase drill press. I am guessing that must be 480 Volts. Check around farmers' auctions. Your single-phase transformed voltage must be applied to two of the three windings of your same-rated (480 V) pony motor. The physical output of your pony motor is simply a balanced flywheel mounted directly onto the shaft, to provide some mass and inertia. A 2 or 3 horsepower pony motor could handle well more than a small drill press. When you apply your transformed voltage (480) to the pony motor, it will hum and refuse to move, since it requires 3 phases to know which way to go. This is the part where you grab the flywheel and give it a good hard spin in the appropriate direction. Your pony motor must be a typical squirrel-cage induction motor. Now the pony motor is not just a load. Its remaining winding, combined with the two others supplied, will add the 3rd phase power at 480 Volts, provided the flywheel does not absorb a significant part of its rated power capacity. The motor becomes a generator. Michael Faraday would be proud. Viola! three-phase power from common household supply voltage. All you have to figure out is where to connect all the wires. Good luck, fellow hole-poker.

How many motor neurons are involved in the descending motor pathways?
two motor neurons are always involved in descending motor pathways. the upper motor neuron and the lower motor neuron.
What type of motor did Nikola Telsa invent?
Alternant motor, polyphase motor and the basic electric motor.
