Q: Why is DC motor wider than AC motor? High speed regulation accuracy? How do you know?: The DC motor has the ability to keep the rated torque from the zero speed to the nominal speed, so it can perform stepless speed regulation from zero speed to rated speed (constant torque).

Q: Im building a formula hybrid vehicle, and Im wondering what would be the difference from using AC and DC motor: DC motors are easier to control, especially using digital (computer) systems. DC Control systems are usually more reliable than AC Control systems AC Motors require a sourcde of Alternating Current, but ALL batteries are Direct Current (DC). Therefore, you need what is called an AC Inverter to make Alternating Current (AC) from Direct Current (DC)batteries. This means more expense, AND more parts that could possibly fail, thus reducing the reliability of the vehicle and making it more expensive to repair.

Q: How is frequency is efecting when a motor running by electric power,What is the relation of KW with FREQUENCY?: Dear Meetantacheri, I am not sure which frequency you refer to: 1) The Power Supply Frequency You need to look in your Ordinary Level Physics Books or on the wwweb at: Synchronous AC Motors Asynchronous AC Motors 2) The Rotational Speed of the Motor: For a DC Motor this depends on whether the rotor and stator are Series or Parallel Connected and the Mechanical Load that is on the Motor. For a Synchronous AC Motor you get field slippage if the mechanical load is too high I am not sure what you mean by the kW / f part. If a motor is overloaded it slows down, takes a lot of current and the power consumption rises. This overheats the motor and the winding are destroyed. (see back-EMF)

Q: i have a 92 cherokee and the ac blower motor quit working, i replaced it with a new but still does not work.?: Hi That leaves the fuse or switch or relay.

Q: can thet be replaced, and how do you do it?: I can’t imagine anyone trying to replace the bearings / sleeves in an electric motor. If you hire it done the cost would be prohibitive if you try to do it yourself with limited knowledge the chances of being successful are very remote. Remove the motor and take it to grangers or any place that has replacement motors in your area and they can match it up Cap and all. Your done ! enough said.

Q: I am doing a project on automation of the Mixing Mc. In the existing Mc, 1 HP AC Single phase induction motor is used for this purpose. I have planned to replace with 1 HP DC Motor with the Battery and inverter to use this mc even during the Power cut times. NOw i require the clarity on the Battery Specifications - 12V or 24 V can be used for his purpose. Required Torque would be 4 Nm 1500 RPM. Pls guide me in proceeding further.: One horsepower is equal to 746 Watts; in reality, however, a 1 hp AC induction motor draws 1500 Watts at 1 hp load. If you use a DC motor, you would connect batteries in series. If you are designing uninterruptable power for an AC motor, the requirements are formidable. First, you need an inverter capable of 1500 Watts comtinuous and 9000 Watts starting surge. Second, at 12 Volts the battery will have to supply 150 Amperes. A back-up supply of this size is not practical as opposed to a standby generator. A suitable inverter will be expensive (if available). The actual battery requirement would be several hundred Ampere Hours of capacity for every 20-30 minutes of operation.

Q: So, my old blower motor started smoking, and sparking, I took it in, and bought a new one, the guy also sold me a new capacator with it, and hooked it up for me... BUT I'm confused which wires go where. I took pictures..: Their are several ways to wire it.. If you want it to connect like the old one with 3 wires you go ahead and connect black to black and plain brown to brown and the brown wire with the white stripe to common or where the orange wire was. You would not use the white wire, tape it off (It will be live,you don't want a short) and out of the way,don't use it. OR go ahead and connect black to black and white to the common side of the contactor and connect the 2 brown wires to the new cap.You would also tape any other speeds like red (low) or blue (medium) off so they won't short to chassis or each other. Treat them speeds as if they is live wires. Tape them off away from each other and the frame.

Q: How do I know whether the motor is a direct current motor or an AC motor?: You didn't know when you bought itYou can have a look at the nominal voltage on the nameplateDC is DC, AC is communication

Q: Hello everyone,I need help wiring up a pump motor that I just got to replace an old one. It is an Ironhorse Rolled Steel general purpose motor rated at 1 HP. It is dual voltage (115/230) but will be running it at 115V. It uses a T1-T8 system the colors are:Blue T1White T2Orange T3Yellow T4Black T5Red T8The wiring scheme for low voltage is:Line 1: Blue orange redLine 2: White Yellow blackHow do I hook this up to an AC power chord that has White, Black, Green wires?: I would take this to mean that line 1 is the black wire,and line 2 is the white wire. The green ground goes to the motor housing. the hot wire (black) is called L1.

Q: The difference between three-phase AC synchronous motor and three-phase AC asynchronous motor: The stator windings of synchronous machines and induction motors are the same. The main difference is the structure of the rotorThere is a DC exciting winding on the rotor of synchronous motor, so the external excitation power supply is needed, and the current is introduced through the slip ring;The rotor of the induction motor is short circuited winding, which generates current by electromagnetic inductionAsynchronous motor has the advantages of simple, low cost, easy to install, use and maintenance. It is widely used. The disadvantages of low efficiency, low power factor of power grid and high efficiency disadvantage. Synchronous motor is a capacitive load, can improve the power factor.
