NORD production of 4 very ordinary three-phase ac motor and three-phase ac braking power range 0.12 kW to 200 kW.Production of motor by NORD for independent brands, the production process does not involve the subcontractor, so there will be no bottlenecks, our customers can enjoy the shortest delivery time.If you use a NORD energy-saving three-phase motor, the maximum can save up to 40% of the energy consumption.NORD efficiency three-phase motor is also in line with the 1992 rules in the energy bill (EPACT) in the United States.
Any applicable national, local and system-specific regulations and requirements must also be observed!
Special designs and design variants may differ with regard to technical details. If anypoints are not clear, it is urgently recommended that you consult the manufacturer stating the type designation and motor number or have the maintenance work performed by NORD.
2.1 Field of Application
Use of the motors:
The motors may only be used for their intended purpose. The motors are designed with at least IP 55 protection (for degree of protection see name plate). They may be installed in dusty or damp environments. The necessary degree of protection and any additional precautions required always depend on the operating and environmental conditions. For outdoor installation and vertical designs,
e.g. V1 or V5 with the shaft pointing downward, NORD recommends the use of the double fan hood option [RDD]. The motors must be protected against intense sunlight, e.g. by means of a protective shield. The insulation is tropicalised.
Installation altitude: £1,000 m Ambient temperature: -20°C...+40°C. With standard motors, a greater ambient temperature range is permitted from -20°C...+60°C. The rated power must however be reduced to 82% of the catalogue value. If the maximum value of the ambient temperature is between +40°C and +60°C, the power consumption can be inversely interpolated linearly between 100% and 82%. The motor connection cables and the cable inlet glands must be suitable for temperatures ³ 90°C.
- Q: What is an ac driver? And the principle! Thank you very much!
- Overload capability The step motor is generally not overloaded. Ac servo motor has the capability of overload. With the example of the panasonic ac servo system, it has the capability of speed overload and torque overload. The maximum torque is three times the rated torque, which can be used to overcome the moment of inertia of the inertia load. Stepper motor because there is no this kind of overload capacity, in order to overcome the inertia moment when selection, often need to select a larger torque of the motor, and the machine during the normal work and don't need that big torque, there is a moment of waste phenomenon. Running performance is different Stepper motor control for the open loop control, start frequency is too high or too much load step easy appear lost or blocked, stops frequently occur high speed overshoot phenomenon, so as to ensure the control accuracy, should handle the ascending and descending speed problem. Ac servo drive system for closed-loop control, the actuator can be directly to the motor encoder feedback signal sampling, internal position loop and speed loop, general won't appear step motor lose step or overshoot phenomenon, more reliable control performance.
- Q: Single phase single capacitance ac motor three wires wrong
- The single phase motor is divided by the main winding and the starting winding, and the wrong turn can also be turned, but the electric opportunity quickly overheat and damage, the proposal to seek a professional to show you.
- Q: When the ac servo motor is turned off, the rotor shaft is tight
- When the ac servo motor is out of power, the shaft of the rotor shaft is very tight: Since the servo motor is the brake device, the motor is not moving when the power is off. If there is no brake device, it indicates that the load is not installed properly, which can cause rotational difficulty. Solution: loosen the load and turn the motor separately.
- Q: Why does ac motor speed control system replace dc motor speed control system?
- The PWM control is the control core of the ac speed control system, and the final implementation of any control algorithm is almost done in various PWM controls. Has been put forward and the PWM control scheme of practical application to more than a dozen, articles about PWM control technology in many famous electric power international conference, such as PESC, IECON, EPE has formed at the annual meeting
- Q: Is it still a communication welder
- Generally speaking, the ac welder appears on the market, the more common is the manual arc welding series, such as: BX1...
- Q: What is the control speed for ac servo motors?
- By ac servo motor drives to work, of course, different types of servo motors have their rated speed, and speed control is achieved by the servo drive.
- Q: Why is it that high speed motors rarely communicate?
- High-speed motor power is small, the production of dc easy, power gain, ac motor are rarely of more than 1500 turns, the high speed rotor of the centrifugal force is too large, high power motor generally do not need such a high speed. Series electric motor can be used for both the dc and dc, high speed, at home food processing machine, handgun drill and so on If you use a converter, you can do special high-speed motors, and the price of the converter is much higher than the motor.
- Q: Three-phase ac asynchronous motor load start and start up with airload start current who small, why?
- Starting the current size doesn't have anything to do with the belt without load, so the boot current is the same size. You can see the equivalent circuit of the motor.
- Q: The difference between a converter motor and a regular ac motor
- From the point of view of the operator, the frequency conversion motor is a bad motor, and the ordinary motor is the good motor. 2) as a result of the inverter output PWM adjustable wide wave simulation sinusoidal alternating current (ac), contains a lot of harmonic, after reactor filter in general need to enter ordinary motor, otherwise ordinary chance fever; 3) in order to adapt to the inverter output PWM adjustable width sinusoidal alternating current (ac) contains a lot of harmonic wave simulation, specialized production of frequency conversion motor, its role in fact can be interpreted as reactor with common motor; 4) that is to say, with the power of variable frequency motor is bigger than ordinary motor iron core section, coil number of turns, wire diameter, higher insulation, a special cooling fan motor; In order to adapt to the need of weak magnetic speed adjustment, the bearing capacity and high speed rotor dynamic balance are considered. 6) this frequency conversion motor does not have a better torque characteristic, but it simply overcomes the need of the ordinary motor to adjust to the PWM for the wide wave analog sinusoidal ac. 7) if the converter motor does not have the above characteristics and requirements, it is a false frequency conversion machine.
- Q: About 100W ac motor is better than dc motor
- Depending on what you do with the motor, each has its own characteristics. The main difference between ac and dc motors is that the power supply is different, the ac motor USES alternating current, and the generator is alternating current. Direct current motors use direct current, and generators emit dc points. The advantage of dc motor (compared to ac motor) is the ability to achieve economic and smooth speed regulation. Ac motors need to be able to do this using a converter, an electromagnetic regulator, etc. Power and speed must be the same speed of dc motor and ac motor, dc motor price is a little more expensive, mainly because it must have a complex "commutator" to realize the ac/dc conversion. This also increases the manufacturing cost of dc motors.
