1. Common faults of motor heating up too high or smoke motor Causes: 1. Excessive load; 2. Two-phase operation; 3. Blocked air duct; 4. The working temperature is too high; 5. Interphase or inter-turn short circuit fault of motor stator winding; 6. Motor stator winding grounding device; 7. The power supply voltage is too high or too low; Overhaul...

Poor choice This should be the situation that friends have encountered the most in the Z, the situation of large horse-drawn carts and small horse-drawn carts is everywhere. The big horse-drawn trolley is not bad, at least there is no big problem in use, the most investment has been added, and the equipment can still operate normally; But the small horse-drawn cart ...

Inverters often encounter a variety of problems during commissioning and use, during which overvoltage is the most common. After the overvoltage occurs, in order to avoid damage to the internal circuit, the overvoltage protection function of the inverter will work, so that the inverter will operate intermittently, resulting in the equipment can not be ...

Whether a contactor is used between the inverter (VFD) and the motor depends on the specific situation. When the contactor is on and off when the motor is running, the operating overvoltage is easy to cause VFD damage. Therefore, whether to use the contactor, it must be based on the actual situation to make the correct ...

With the passing of time, the inverter has now fully penetrated into the work of major industries. In our daily use, we will inevitably encounter all kinds of problems. For example, I forgot the cipher code of the inverter. See here ...

Sunland inverter and soft start is a first-class, reliable and reliable motor control system, which is able to meet the needs of various applications. The advantages of expected Sunland inverters and soft start are: 1. Performance: Expect Sunland inverter and soft start...

1. The inverter itself has strong electromagnetic disturbance, which will disturb the operation of some equipment, so we can add a cable sleeve to the output cable of the inverter. 2. The control line in the inverter or control cabinet is spaced at least 100mm, and the power cable is at least 100mm. 3. In the purchase of inverter ...

(1). The deceleration time of the frequency conversion parameter is increased or free parking is adopted Assuming that the overpressure phenomenon is present in the parking process, the process has no parking requirements for the parking time or direction, and the deceleration time can be increased appropriately. The reason for the overvoltage in the parking process is that after the frequency conversion announces the deceleration command, the motor ...

Capacitor damage is the highest problem in electronic devices, especially electrolytic capacitors. Capacitor damage is manifested in: 1. Capacity becomes smaller, 2. Capacity is completely lost, 3. Leakage, 4. Short circuit. Electricity...

There are many control methods for inverters for fans and pumps, which can be selected according to specific conditions. Here are a few common scenarios. (1) Manual adjustment This is the simplest control method, that is, the operator instructs according to the instrument, ...

A. Wound rotor asynchronous motor The rotor winding of the wound rotor asynchronous motor is a set of three-phase windings with star connection. The end points of the three-phase winding are connected to the three collector rings, which are connected to the brushes and the external resistor (for starting or speed regulation) through the collector rings. Select inverter ...

SB150 SB150 is a delicate and practical inverter launched by Sunland, with exquisite and delicate appearance, exquisite and perfect circuit, simple and practical function, and clear and reasonable menu distinction. At the center of the SB150 is Sunland's high-performance optimized space vector ...

Voltage Space Vector (SVPWM) Manipulation Method: It is based on the premise of the overall generation effect of the three-phase waveform, with the intention of approximating the ideal circular rotating magnetic field trajectory of the motor air gap, generating the three-phase modulation waveform at one time, and controlling it by approaching the circle with inscribed polygons. In practice, ...

There are many setting parameters of the inverter, each parameter has a certain selection scale, and the inverter can not work normally due to the improper setting of individual parameters in use, so it is necessary to set the relevant parameters correctly. ...

1. The motor slows down too slowly 1) If the deceleration time is set too long, reduce the deceleration time 2) Install a braking resistor 3) Add DC braking 2. The motor is overheated 1) The load is too large, and the practical moment has exceeded the ...

Hope Sunland Technology Co., Ltd. is a national key high-tech enterprise dedicated to the research and development of high, medium and low voltage frequency conversion technology and the design, development, production, sales and service of related products.

When various factory equipment uses frequency conversion speed regulation, harmonic disturbance will occur on the power supply side and motor side of the inverter (VFD), which will form electromagnetic disturbance to the power supply network and other electrical equipment near the VFD. In addition, in order to ensure the long-term reliable operation of the VFD, the wiring of the VFD is very important. ...
