The yvf2 series (ip54) variable frequency speed regulation three-phase asynchronous motor independently designed, developed and produced by our company is the second generation product of the yvp series variable frequency speed regulation motor. The influence of high-order harmonics on the loss and efficiency of the motor, shaft voltage, impulse voltage and dielectric strength when the frequency conversion (non-sinusoidal) power supply is supplied, adopts a special f-class insulation structure that can withstand high-frequency pulses and anti-corona The corresponding relationship between the grade, frame number and installation size is consistent with the y2 series three-phase asynchronous motor, which conforms to iec, and has strong interchangeability and versatility. And the independent power supply cooling fan is used to cool the surface of the motor by forced ventilation, which ensures that the temperature rise of the motor does not exceed the allowable value when the motor runs at low speed and constant torque for a long time.
YVF2 series variable frequency speed regulation motor is used for AC speed regulation in the form of "inverter + cage induction motor (special variable frequency motor). It is widely used in metallurgy, petroleum, chemical industry, medicine, textile, plastic, printing, packaging, food and other industries. It is used in the fields of machinery, pumps, conveyor lines, automation equipment and machine tools. The use of polymer insulating materials and vacuum pressure dipping manufacturing technology makes the electrical winding insulation endurance and mechanical strength extremely strong, which is sufficient for high-speed operation of the motor and resistance to frequency converters. High-frequency current impact on insulation damage; has a wide range of constant torque speed regulation characteristics, stable speed regulation, no torque ripple; has good parameter matching with various frequency converters, with vector control, can achieve zero speed full torque , low frequency and high torque, high precision speed control, position control and fast dynamic response; high balance quality, vibration level is R (vibration reduction level); forced ventilation cooling system, axial flow fan is ultra-quiet, long life, strong wind, Ensure that the motor is effectively dissipated at any speed, and can achieve high-speed or low-speed long-term operation. This series of motors has passed CE certification.
yvf2 series motors can be matched with frequency conversion devices of various control methods at home and abroad to form an AC frequency conversion speed regulation (open loop) system. The device forms a closed-loop control system. This series of motors can achieve constant torque speed regulation of more than 1:50 and constant power speed regulation of more than 1:4, with excellent fast response, good dynamic performance, reliable operation, and easy maintenance. The troublesome DC motor can be widely used in metallurgy, light industry, papermaking, textile, machine tool, petrochemical and other industries. The rated voltage of yvf2 series motors is 380v, the rated frequency is 50hz, 45kw and below are 5-50hz (3-50hz above 45kw) constant torque operation, 50-100hz is constant power operation, power ≤ 55kw is y connection, Power > 55kw is △ connection. Various voltages, rated frequencies and speed ranges can also be designed and manufactured according to customer requirements.
YVF2 series variable frequency speed regulation three-phase asynchronous motor (center height H63≤355mMSEE0.12≤315kw) is a new generation product. This series of motors adopts computer-aided design. the design of. Selecting a reasonable electromagnetic load can suppress and reduce the adverse effects of harmonics and a series of motor harmonics.
In the range of 1:10 speed regulation, the motor can not only run smoothly, but also have no torque ripple. It also ensures the overload capability of the motor at high frequencies. This series of motors has wide vibration and low noise.
Compared with the speed regulation system composed of SPWM frequency conversion device, YVF2 series variable frequency speed regulation three-phase asynchronous motor has obvious energy saving effect, good speed regulation performance, wide speed ratio, fast response, good application range and high performance-price ratio. One of the best systems in the speed regulation scheme.
By cooperating with high-precision sensors, it can be widely used in the spindle drive of dry CNC machine tools, constant torque and constant power speed regulation in industries such as textile, chemical and metallurgy, and energy-saving speed regulation of fan pumps. High-precision closed-loop operation can be achieved.
YVF2 series variable frequency speed regulation three-phase asynchronous motor improves the protection level and insulation level and reduces the noise. Novel and beautiful installation dimensions and power levels meet IEC standards for interchangeability. This series of motors adopts an independent cooling structure, which forces the axial flow fan to ventilate and cool, so as to ensure that the motor does not exceed the allowable value when running for a long time at low speed and constant torque.
