- Q: Brushless DC motor is AC motor or DC motor, why?
- The DC motor only has no brush and commutator. It should be inside to check the rotor position through the Holzer sensor, make the drive circuit turn over, and make sure the motor turn in one direction
- Q: Is the 380V single-phase AC motor the same as that of the 220V AC motor?
- Dissimilarity。 220V is followed by a line of fire, a zero line. 380V's got two fire lines.
- Q: The motor is out of a dryer (240 VAC) so there is lint build-up in the motor's grease. The casing seems to be a cast iron that has been... connected... not welded, not screwed together. I see no way to get the case open to pull it apart. I can get it working properly for about 24 hours using generous amounts of WD-40, but the motor builds up some physical resistance after this time. I feel I need to clean the contacts, and relubricate the motor. I can see the contacts as the case only holds everything together, and does not fully enshroud the windings. What can I use to clean the motor without dissasembling it further, or how can I dissasemble the case (if you have come across this before you know what I mean). I am an apprentice electrician so I already understand the safty concerns of fixing an appliance.
- I am not sure what you mean by contacts. (an electrican for over 30 yrs having rebuilt and repaired many motors ). I assume you mean the armature?or the coil or stator? Some motors like your standard electric drill uses brushes that are made of carbon, but in your case i dont believe thats what your talking about. Yes cleaning the windings and other parts of the electrical end willhelp but not really in your case. what i believe is happening is that your GREASE which is set usually inbearings or surround the actualy moving parts needs tobe replaced or repacked... and if you have bearings they toomay need replacement
- Q: What is the difference between AC motor speed and DC motor speed?
- Alternating current dynamoAC motor is rotating to produce a rotating magnetic field formed by the stator voltage in the rotor should be on the.The speed is generally fixed speed. But because of its simple structure and convenient power supply, it is widely used in industrial enterprises. Small to household refrigerators, washing machines, vacuum cleaners, large machine tools, and so on, all use AC motors.
- Q: can DC or AC motor run with using diesel??
- A generator can.
- Q: How to ac motor work?
- Hi it works by using the alternating currents causes flux changes which cause rotation of the field and stator currents. hence rotation the stator can be a laminated solid armature as the field rotates around it. unlike a dc motor where the commutator does the switch with the brushes.
- Q: and act as a brake or actuator? I realize an electric motor can act as a brake but can its position be locked solid?
- In some inverter controlled cases, the VFD controller can hold 0 speed using various methods such as a DC hold, or plain speed control. Locked solid is relative to the the slow speed characteristics of the motor.
- Q: it is small powerful motor and light i wanna use it as a motor for my RC plane any help!!!
- If your motor is universal,one with armature and commutator segments and carbon brushes,it can run on dc power, but, if it isn't, your motor won't run on dc power.
- Q: Why is AC motor control more difficult than DC?
- Motor control, generally refers to speed regulation".AC motors are different from the mechanical characteristics of direct current motors,The mechanical characteristics of the DC motor are 1 slightly downward inclined "straight lines", the relationship between its speed and torque (characteristic) is relatively "hard", and it can easily change its speed by changing the power supply voltage of the motor;
- Q: and some formulas for calculating electric motor speed
- AC motors usually have the following on the nameplate: Rated output power – Pr (kilowatts – kW or Horsepower – Hp) Rated speed – nr (revolutions per minute – RPM) Rated voltage – Vr (volts – V) Rated frequency – fr (hertz – Hz) Rated current – Ir (amperes – A) Other parameters (not on the nameplate): Rated torque – Mr (Newton meters – Nm or pounds feet – lbs-ft) Mr=9550xPr/nr for Mr in Nm Pr in kW Mr=5252xPr/nr for Mr in Hp Pr in lbs-ft Number of poles – p (always an even number, only north/south pairs are possible) With 3-phase induction motors, speed can be increased or decreased by changing the frequency: Speed, n = 120f/p To have available torque remain constant at M = Mr without current exceeding rated current, voltage must be increased or decreased with frequency change such that V = f x Vr/fr. Speed increase is limited by the motor’s ability to tolerate the electrical stress due to increased voltage and the mechanical stress due to increased speed above the rated values. If the frequency is increased above the rated value without increasing the voltage, the available torque will be reduced. Up to about 50% above rated speed, the available torque is approximately the torque that will produce the rated output power. Under some load conditions, some types of single phase motors can be controlled in the same way to a more limited extent. Under some load conditions, with some types of single phase and three phase motors voltage reduction can be used to reduce speed to a limited extent.
