Overview

This series motor adopts modular design. It consists of four parts: torque motor, eddy current regulator, electromagnetic brake and fan, which can be flexibly configured to
meet different customer demands. With introduction of a new special brake, it can cater for outdoor and high-altitude operations. The product has reached the international
advanced level with the patent for utility model. It is mainly used as a trolley speed-change gear for tower crane as well as other mechanical equipments requiring for
constant power and stepless speed regulation.

FeaturesConstant tension and linear speed, stepless speed regulation, frequent starting;
Special eddy current regulator for the motor realizes smooth startup or stop;
New special brake (national utility model ZL201120188173.2, ZL2011201881643). This ensures fast braking and accurate positioning with higher safety and reliability
Besides, manual release is possible;
The rotor is made of copper alloy with better mechanical properties and mechanical bearing capacity in the domestic industry;
Spindle is hot forged by alloy structural steel，with good overall mechanical perlormancc;
A thermal protection component is buried into the in stator winding, making motor more safer and reliable;
Compact structure, small volume, lightweight as well as high reliability, so itfeatures easy maintenance and repair.

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?: not an ordinary one. A stepper motor can. Blocking movement with an ordinary motor, normally possible only if gearing is involved and a delicate adjustment of forces/current is done requires a fairly high current flow and can burn out the stalled motor.

Q:I want to make a Brush-less DC motor that goes 1720 Rotations Per Minute while carrying a 70 kilograms load on it. The motor must be 50mm in diameter and about 15mm in width.How do I go about making that and what kind of specifications must a battery have, to be able to run this for 1-2 hours?Thank you in advance! :): Dc Motor Questions

Q:Is the single-phase carbon brush motor a direct current motor or an AC motor?: (1) motor is a DC motor with single-phase brushless motor or AC, there is also some DC motor AC and DC motor, such as most of the pistol electric drill AC and DC motor, AC and DC power can also be used to use.(2) the power supply of rectifier bridge is not from positive and negative pole, and the power supply of rectifier bridge must have positive and negative poles, otherwise it is not power supply of rectifier bridge.(3) bidirectional thyristor should be used in AC circuit. If your motor speed is bidirectional thyristor, it may be AC and DC motor.DC motor carbon brush and AC motor carbon brush is the same, so there are AC and DC dual series motor.

Q:without adding any gearing or uping on the size,wattage, etc.: No, not really. As with any motor, you are going to get X power out for Y power in. Power in is electrical wattage, and power out is mechanical wattage (or horsepower). Electrical power is volts times amps, and mechanical power is speed times torque. You can't get more power out- increasing the torque- without more power in. The only practical way to do this would be to feed the motor more power (in the form of voltage), but that would increase your power consumption, increase your speed, and you're not likely able to get a higher AC voltage very easily.

Q:alternators: In theory it would work. Rotational energy in an alternator turns into DC current. So theoretically, if you put DC current in, rotational energy should come out. Just like spinning an electromagnet inside of coils of wire makes electricity, putting current through the wires rotates the electromagnet. Good luck!

Q:My AC induction motor has to run in indexing table application which works 24X7. Each cycle has 1.2sec (0.2sec idle). Hence per hour the motor has 3000 cycles. Iam having forced cooling fans on motor to dissipate the heat generated due to high start/stop. My motor brake (AC) releases within 0.04sec engaging within 0.007sec. hence the total braking action is about only 0.47sec. Pls tel me the 0.2 sec is enough for idle condition of motor.: In order to answer this you need to know 1. The motor torque and current vs time. 2. The power lost in the motor. 3. The motor temperature rise per watt of power loss with and without the fan.

Q:How can I control the RPM of an industrial motor of 7 horse power? I need it to have high torque and low RPM, like 100 per minute.: If you have a way to decrease the AC input frequency thats the easiest way. Depending on the application of the motor you can have it maintain a certain RPM and simply change the power to it (by changing the amps applied) to change the HP it puts out, but that is really only certain applications

Q:I check with our supplier. they told me that we have to load on motor then only it will show correct rpm ( both low and high). what is the maximum load for this motor It is shoiwng 1.3 amp: DOES THE MOTOR HAVE A 2 SPEED switch, and what are you using it for? 1.3 amps has to be 120 volt. its probably a 2 speed motor without a switch. in that case it has to be under a load. if this helps you cant hear it change speeds, even under a load, i really need more info before i can help you. how are you checking the rpms? butch

Q:I am replacing a fan motor in my AC unit. I have few questions. First of all, the wire that comes with motor is not in sufficient length to connect to the connector, How can I extend those wires? Secondly, The fan motor suggests to use only 340 V two prong small condenser, but the original condenser have 3 prong connection. So, Do I need to connect the small one along with the original one? Also, previous motor has only 3 wires *black, purple and brown) but the new motor has 4 wires (brown, brown-white, yellow and black). So, I am confused. Any help would be greatly appreciated.: two brown wires should go to the new capacitor (has to match what motor calls for) that you should have brought with the motor. Yellow and b lack are power wires, so just make sure they get 220V when unit turns on, top of cont actor or if heat pump one black wire goes to defrost board other to other leg of 220. Remove any extra wires. Make sure to take any drain plugs on the bottom of motor if down mounted, so can drain water. After installation check amp draw to make sure motor fits application. You should have diagram on motor and cover of unit to help you. If reversible motor make sure fan turns against the riviots in the blades

Q:if a 3 phase motor is rated at 100 amps how many amps is that per phase?: 33 6666666666666714112/20000000000000000000
