Overview
YZTDE series motor is a mufti-speed three-phase asynchronous motor with special brakes attached to its tail, which is exclusively designed for the tower crane and other similar lifting
mechanisms (with national utility model paten)
Features
Big speed regulation ration, ideal ultimate ratio, high efficiency and big lifting torque;
Small starting current, simple and convenient control with high reliability
Athermal protection component is buried into the winding, which can be wired to motor temperature control& protection system, so the motor operation is more secure and reliable;
'the brake (fitted with special manual release device) is a de-energized brake type (with national utility model patent, Patient Iho. GL201120188124.9. LL201120188123.4)一it has big
braking torque and short response time. Due to very small mechanical noise during switching, it enables quick braking and accurate positioning
Made of a novel structure at the shaft end, it has good seal effect and long service life up to 3000h;
Compact structure, small volume and lightweight
User's Options
The user may select the motor with or without speed sensor where necessary. This is confirmed by the user when signing the contract
- Q: What will happen when we give more voltage but same power into an AC motor ?Can we calculate the RPM and TORQUE that the 1Kw AC motor will produce when we give it ( input ) :1. 200 VAC 5.0 Ampere2. 400 VAC 2.5 AmpereWhich input will make the faster RPM ?Which input will make the stronger TORQUE ?
- The most commonly used AC motors are induction or synchronous motors. Their speed is determined by the frequency of the supply and not by the voltage. If 200 VAC is the motor's rated voltage, then doubling the voltage to 400 would theoretically mean that the current needed to supply the load torque is reduced to half. So (in an elementary consideration) nothing would happen to speed but current would be halved and power would be the same. it is anyway the load which basically determines the power required - i.e. you don't give the power in, it is the load which draws it from the source via the motor. In practice however the above would not work. The doubled voltage would need to double the flux in the motor to generate a back-emf. It could not do this because the magnetic circuit would run severely into saturation. You would get some reduction in the current needed to supply the load but a large increase in magnetising current. Windings and core would overheat quite fast and fairly soon you'd burn out the motor due to insulation failure. The insulation design would be based on 200V and a certain temperature limit (say 130 C). At double voltage and under overheating it would not hold out long. If it held long enough, then the core (at high saturation) would eventually burn out.
- Q: i need help with a school project. im in high school.
- Yes. a magnetic field definitely affects an electric motor. That coil of wire in the middle of an electric motor is charge and becomes an electromagnet when it is powered on. On the outside casing there are magnets as well. For every 1/2 revolution of the motor (DC motor), the polarity of the electomagnet is switch so that the polarity of the electromagnet is always the same as the magnets on the external casing. This causes the magnets to always repel each other and is what keeps the motor spinning. The mechanism by which the polarity switches is a bit different in an AC motor, but the overall principle is still the same.
- Q: are there any batteries that produce alternating current?could i put in a little alternator?
- It is possible but it will all depend on the size of the motor There are no batteries that produces ac unless an inverter circuit is inserted to have ac at the output
- 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: What kind of current flows in an AC motor rotor bars? (AC or DC)?
- AC; in an induction motor the rotor current is caused by the induced AC voltage.
- Q: How to make the AC motor stop rotating rapidly?
- A, electromagnetic brake.Two, use YEJ motor with brake itself, it also and ordinary Y series three motor mounting dimensions are exactly the same, but with a little bit length.
- Q: Replacing fan motor on AC condenser?
- There is no fan motor on the condensor. The fan is on the radiator. The other fan that also operates the heater is on the evaporator end.
- Q: theory of operation of synchronous motors?
- Theory okorder /
- Q: I have an AC motor that has a resistor. Why are resistors used? Any answer is appreciated. As simple as you can. Thanks
- AC motor does not need a fix resistor ! Perhaps it was a capacitor ? Show the picture if you could or read what it marked on it.
- Q: Can current transmitter and VFD be used for the same motor?
- hi you have already asked this question you will need to stop using acronyms we need to know what a current transmitter is and a what a VFD is as neither make any sense.
