This serial products consist of wound rotor three-phase asynchronous motor,centrifugal fan and break-type electromagnetic brake. The
rmistors are embeded in stator winding
The motor brake is connected with shaft by spline. It is equipped with manual release device,which relieves the brake in the case of power
failure, so that it is easy to install and commission the motor or set down the heavy objects in the condition of failure
This type motor rotors are specially designed. Referencing the French technology, the shaft ends are closed by new-type hermetically
sealed construction, and the vriginative electromagnetic brake extends the life of motor airtight. When throwback is activated, the mechanical
and current impacts are smail,and also the vabration and noise are small. The comprehensive performance of this serial motors is greatly
enhanced
This type motors can be used to substitute those imported from France.
- Q:Here is the question: Some motors must be able to switch directions, sometimes spinning clockwise and other times counter-clockwise. For example, the motor in a VCR must fast forward and rewind videotape. In these situations, explain which type of motor is the best choice. Could someone please help me understand? Everyone is saying it's DC, but I don't understand why.
- A motor of either type has 2 wires. If an a.c. type motor, it matters not which way round you connect the a.c. supply to the motor: it will always spin the same way. A d.c. motor will reverse its direction of rotation if the wires are switched over.
- Q:I've read that it's because they don't require commutators but i couldn't understand that part .. can someone please explain in some details or offer me a useful link
- Wrong , high power high torque motor is series motor, not the induction motor. AC induction motor is widely used because it is simple to make and less maintenance. Its rotor just a piece of iron core without the need of winding, no need the brushes like DC motor, therefore it does not need maintenance from time to time like other type motor.
- Q:I am looking for ideas on AC electric cars. i have seen the kits that use an AC motor and an inverter unit to convert the battery power for use in the motor. I am wondering if there is any advantage to using a VFD and an appropriate size generator? I know locomotives use the motor/generator set up with good efficiency. if i wanted to use a 20hp induction motor i wonder how i would pick a VFD and a generator so as to make a reliable set up? thoughts?
- The Toyota Prius uses an AC motor Nimh batteries and a 4 cylinder petrol motor. It has all the control circuitry for regenerative braking, etc already developed. It has no provision to charge the battery from teh household supply. All power comes from the petrol motor. There are 3 models shown at the site below Electric Motor Operating Voltage 1997, 288V 2000, 273V 2003, 500V Power 1997, 40hp 2000, 44hp 2003, 67hp

- A lot of motors have 6 wires for the three windings, so you can connect them as star or delta, as required with a star delta starter. The voltage ratings will tell you though. If it is a 380V, 415V, 440V etc. motor and it is connected as star it has a lot less power. If its 220 you have to figure out whether that was for a 127/220 or a 220/380 system. As a check, ((W x 1/PF) / Amps) from the nameplate gives the phase to neutral voltage, or W/A is close enough to tell. Always check the running current when you have installed a motor. Don't forget that the phase rotation may be important for a pump. If a water pump goes backwards there is steam and boiling water everywhere.
- Q:Hey guys. Not to long ago did I replace my AC resistor for my car. Its no hassle to replace but what dawns me is the fact that my old AC resistor that I replaced was burned, it literally looked like it caught on fire. The plastic melted and had some burned holes. This really puzzles me and scares me because I do NOT want my truck to catch fire because of the AC. Would you guys know any reasons why it would just burn like that? anyway to prevent it? I barley use the heater. Living in California you don't have that many cold days here accept the morning and I just use the heater to defrost my windshield and that's it.
- Another possibility is the blower motor could be drawing too much power, causing frequent resistor trouble.
- Q:Brushless DC motor is AC motor or DC motor, why?
- Brushless motor is a direct current motor.Adopt DC work, adjust pulse speed by adjusting pulse width.AC motor works by alternating current and adopts frequency converter to adjust speed.
- Q:Can any AC motor 220 and 380V control positive inversion? What are the conditions?
- All three phase motor, the 3 phase line in any two lines can be switched to control the motor positive and reverse, commonly used AC contactor control, reverse switch control (small capacity) and so on.Single-phase capacitor running motor ends of the main winding or secondary winding can be controlled on the motor is reverse.
- Q:Does a 1 HP motor draw more wattage than an AC one at the same EMF?
- 1 HP is 746 watts. It doesn't matter if it is a 120vac motor or a 240vac motor. A 120vac motor will draw 2x the current than a 240vac motor to develop the same HP. A 1 HP, 120v DC motor still draws 746 watts. But a DC motor can't run on AC power, nor can and AC motor run on DC power without some sort of inverter or converter. The matter of efficiency is something else. Some of that power used to develop 1 HP is lost to friction or heat.
- Q:just bought an inverter. is it possible to connect a small motor with alternator to the AC generated by the inverter, and then use as a charger to charge the battery connected to the inverter so that as the battery is giving power to the appliances connected to the inverter, the charger is charging the battery thus ensuring that the battery wount go down?
- Yes... with the understanding that: You have created a circuit of the power utility, inverter, charger, and battery. In that order. I'm unsure why, however, that you would connect the battery to the inverter. Just make sure that the inverter can do that first. Sometimes there may be alternative voltages on the output of the inverter. If you want an uninterruptible power supply, just keep charging the battery, and don't connect the output of the battery to anything else but appliances designed for your battery.
- Q:I am in the process of learning about and building an electric go kart. I have several questions and am seeking help on electrical issues. I would like to power this kart with an electrical motor and car batteries, possibly chained together for more amps. I have several large AC motors and was wondering if a car adapter like this one
- Start with a DC motor and car batery. Once you master that, upgrade to your AC moter and AC/DC converter and power conditioner. First law of motors: Speed of DC motor controlled by voltage. Speed of AC motor controlled by cycle frequency.
