FENNE KG motor, German FENNE KG model, FENNE KG price

FENNE KG motors are a new generation of gear reduction motors, featuring compact size, low noise, maintenance-free operation, and an attractive appearance. The speed ranges from 0.83r/min to 300r/min. This series of low-speed motors is a new high-tech product that integrates electromagnetic drive and reduction mechanism within the motor housing. The low speed and high torque directly meet customer requirements without the need for additional reduction devices. The motors use Class B and Class F insulation, with protection ratings of IP44 and IP55, and voltages of 220V and 380V.

FENNE KG motor excitation method

Motor excitation method refers to the way the magnetic field is generated in rotating electrical machines. DC motor excitation methods are divided into four types: separately excited DC motors, shunt-excited DC motors, series-excited DC motors, and compound-excited DC motors. A DC motor in which the field winding has no connection to the armature winding and is supplied by another DC power source is called a separately excited DC motor. Permanent magnet DC motors can also be regarded as separately excited or self-excited DC motors, generally referred to directly as permanent magnet excitation. In shunt-excited DC motors, the field winding is connected in parallel with the armature winding. As a shunt generator, the terminal voltage generated by the motor itself supplies the field winding; as a shunt motor, the field winding and armature share the same power source, and its performance is identical to that of a separately excited DC motor. In series-excited DC motors, the field winding is connected in series with the armature winding, and then connected to the DC power source. The excitation current of this type of DC motor is the armature current. Compound-excited DC motors have two field windings: shunt and series. If the magnetomotive force produced by the series winding is in the same direction as that produced by the shunt winding, it is called cumulative compound excitation. If the directions of the two magnetomotive forces are opposite, it is called differential compound excitation. DC motors with different excitation methods have different characteristics. Generally, the main excitation methods for DC motors are shunt, series, and compound; the main excitation methods for DC generators are separate, shunt, and compound.

FENNE KG motor applications

The motor requires only a single-phase power supply, so it is widely used in small equipment for production and daily life. However, due to its relatively poor economic performance indicators, it is only manufactured in low power ratings. Single-phase resistance-start asynchronous motor. Power ranges from 60 to 370W. Its feature is that no external phase-splitting component is added; it starts using the resistance of the auxiliary winding itself, and a centrifugal switch cuts off the auxiliary winding at the end of starting. The structure is relatively simple. It has medium starting torque and overload capacity, making it suitable for small machine tools, blowers, and medical machinery. Single-phase capacitor-start asynchronous motor. Power ranges from 120 to 750W. It is a single-phase motor that starts by increasing the starting torque using an external capacitor. An external capacitor is connected in series with the auxiliary winding, and at the end of starting, a centrifugal switch disconnects both the auxiliary winding and the capacitor from the power source. Like the BO2 type, it operates with only the main winding, while the auxiliary winding remains idle. Capacitor-start motors have higher starting torque but medium overload capacity. They are suitable for air compressors, refrigerators, washing machines, grinding mills, threshers, and water pumps. Single-phase capacitor motor. This is a single-phase motor that uses one capacitor for both starting and running. The auxiliary winding, capacitor, and main winding all participate in operation. Therefore, no centrifugal switch is required. Through proper design, an ideal rotating magnetic field is formed during motor operation, resulting in good running performance, high efficiency and power factor, and low noise. Its power range is 4 to 250W. Since one capacitor is used for both starting and running, considering the pros and cons, because the starting time is very short, when selecting the capacitor value, priority is given to meeting the needs of long-term operation, so a cheaper, smaller-value capacitor is selected. Therefore, this type of motor has lower starting torque and can only be used in machinery that starts under no-load or light-load conditions, such as electric fans, ventilation fans, and tape recorders. Due to the higher power of dual-value capacitor motors, the required capacitors are much more expensive. These motors have good starting and running performance. They are suitable for household appliances and small machine tools.

FENNE KG motor maintenance

Motors should be kept clean at all times, and no debris is allowed to enter the interior of the motor; air inlets and outlets must remain unobstructed. Use instruments to monitor power supply voltage, frequency, and motor load current. Power supply voltage and frequency must comply with the data on the motor nameplate, and the motor load current must not exceed the specified value on the nameplate. Otherwise, the cause must be identified and measures taken; operation can only continue after the unfavorable condition is eliminated. Take necessary means to detect temperature rise in various parts of the motor. For wound-rotor motors, pay close attention to the contact pressure, wear, and sparking between the brushes and slip rings. When the motor is stopped, disconnect the switch in the stator circuit, then move the brush lifting mechanism to the start position and disconnect the short-circuiting device. Regular maintenance is performed after motor operation, generally divided into minor repairs and major overhauls. Minor repairs are general inspections without major disassembly of the motor starting equipment and overall assembly, approximately once every quarter. Major overhauls involve disassembling all transmission devices and all motor components, conducting comprehensive inspection and cleaning of the disassembled parts, generally once a year.
