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: The structural difference between ac motor and dc motor
- direct starting startup slip is 1, rotor induction electromotive force is very big, the rotor current is very big also. When under the rated voltage of the motor starting, referred to as direct start and direct start current of about 5 to 7 times of the rated current. In general, under the rated power is 7.5 kw small capacity of asynchronous motor can be directly starting. Direct starting control circuit used appliances including combination switch, button, intermediate relay contactor, thermal relay, and fuse. Mastering their respective characteristics, at the same time grasp the fuse fuse rated current calculation. Starting control circuit directly: to grasp its control principle. (2) the squirrel-cage asynchronous motor step-down starting. Master star - Angle starting and autotransformer step-down starting the work principle of (3) the wound rotor three-phase asynchronous motor starting General understanding. 6. The three-phase asynchronous motor and reversing control Generally understand 7. Three phase asynchronous motor speed regulation This part is important, to understand the formula. Changing the rotational speed of the motor, there are three possible change frequency and change the winding of magnetic pole logarithmic or change slip. 8. Synchronous motor
- Q: The voltage must be, what is the speed of the motor What is the rated voltage of the motor in alternating current? (with winding winding number)
- The number of wires in a coil is not necessarily the number of turns, but the number of wires in a coil is equal to the number of turns of the coil when the number of wires is equal to one. Have the following relations: the number of a coil of wire around along with all the number x number of turns of stator per slot number of wires is to point to in a single layer winding, each slot wire number is equal to the number of turns; In the double layer winding, the number of leads per slot is twice the number of melons and the number of turns.
- Q: What does the motor center of the three-phase ac motor mean
- Center height refers to the height of the motor shaft to the base Angle of the seat. The length of the machine is used in the international letter of the letters: the "S" - the short stand, the M - the engine seat, the L - the long machine seat, is usually determined according to the length of the stator iron core. The "H" of 80 is 80mm.
- Q: Comparison between ac motor and dc motor
- The advantages of a dc motor The dc motor has good starting characteristics and speed regulating characteristics The torque of dc motors is greater It's cheaper to repair. Dc motor is more energy-efficient than communication.
- Q: How does the ac motor work? What can you do to change why?
- Changing magnetic field generated by the alternating current coil rotor cage in the change of current, the current changes in the change of magnetic field, two magnetic fields interact with each other, caused the cage with the center of the rotor shaft torque, to work,
- Q: What is dc and ac servo motor?? What are the features?
- Upstairs said too much load is professional enough ` ` ` ` ` ` dc servo motor servo motor is better in terms of regulating speed But in the ac servo motor in with local power was not rarely used ` ` ` ` ` ac and dc servo motor has brought my brush There are ac motor without brush with brush can adjust the power of the rotor to realize the speed of the motor But in a motor with brush need to use a period of time will have to change the brush each have an advantage See you in what place ` ` `
- Q: Juicer, dc motor or ac induction machine?
- Using the single-phase 220 V alternating current series motor, the control circuit is extremely simple, only needs the main switch and the protective switch.
- Q: How do ac motor maintenance and maintenance?
- The motor should always be kept clean and not allowed to enter into the motor. The inlet and outlet must remain open. Use instrumentation to monitor the voltage, frequency and load current of the motor. Power supply voltage, frequency, to comply with the motor nameplate data, motor load current shall not exceed the specified value, the plate of or to find out the reason, take measures to bad situation to eliminate the rear can continue to run. Take the necessary means to detect the temperature rise in each part of the motor. The contact pressure, wear and spark of the electric brush and the collector ring are often noted for the wound rotor motor. When the motor is suspended, the switch in the stator circuit should be disconnecting, then the brush lifting mechanism should be switched to the starting position and the short circuit device. The electric motor is repaired regularly after operation, usually in minor repair and major repair. Minor repair is a general maintenance, not big to the motor start device and a whole disassembly, about one in the first quarter, overhaul to all parts of all transmission device and motor is removed, and will remove the components of a comprehensive inspection and cleaning, usually once a year
- Q: Any 220V ac motor can be reversed?
- The four wires can be reversed by changing the direction of the starting winding. It is possible to distinguish between resistors and resistors, and generally start winding resistance greater than the main winding. The capacitance is in no direction, so there is no change in the direction of the motor in the direction of the capacitor.
- Q: Single phase capacitor ac motor speed regulation why does not have corresponding frequency converter
- Single-phase ac motor from principle is converted by the three-phase ac motor, is just one of the phase is generated by capacitance mobile phase 90 degrees, if meet with frequency conversion governor drive the work by the capacitance of the problem. The variable frequency governor has the input single phase 220v, the output three-phase 220v variety, only choose star/Angle 380v / 220v three phase motor to work.
