MV33 is a full system of high energy efficiency design, to meet IE5 and permanent magnet motor national standard level I energy efficiency, because IE5 and permanent magnet national standard level I energy efficiency on some power motor efficiency values are different, MV33 motor in the design of the two standards under the same specification of the highest energy efficiency value. In addition, the MV33 supports the expansion of IE6 energy efficiency, which reduces the loss of IE6 motors by 20% compared to IE5 motors.

It is worth mentioning that the energy efficiency level of the motor is nominal according to the efficiency value of the rated point of operation of the motor, and the high efficiency area of the general motor is near the rated point. However, when the customer is in actual use, most of the motor conditions are not long-term operation at the rated point, which means that many motors are in use, the actual efficiency is lower than the nominal value. For this scenario, we put forward the concept of double “90”, MV33 motor can achieve efficiency above 90% in 90% of the work zone. As a practical case, in a certain variable speed constant torque application scenario, MV33 compared with the ordinary round line design of IE5 permanent magnet motor, 5X00846G01 the overall energy saving is about 2%, and after conversion, it can save 3~6 thousand yuan per year. In the same scenario, the energy efficiency gains of MV33 will be greater than those of IE3 asynchronous machines.

Minimum size and high energy efficiency

Derived from the flat wire hairpin technology

Whether it’s the world’s smallest IE5 energy-efficient low-voltage industrial motor or scalable IE6 ultra-high efficiency, both of these features of the MV33 are derived from flat wire technology.

Compared with the traditional round wire motor, the flat wire technology motor is more conducive to the improvement of the slot filling rate, that is, more copper wire can be filled in the stator slot without changing the space. Compared with the traditional round wire, the slot filling rate of the flat wire motor can be increased by more than 20%, so that the motor can generate a stronger magnetic field. In addition, compared with the round wire winding, the flat wire motor end size is reduced by 30% to 50%, so that the MV33 can achieve an idealized small size.

Some people may wonder, the motor is so small, how reliable? There are three main factors affecting the reliability of the motor: bearing, insulation system and demagnetization of the permanent magnet motor.

How does the MV33 work?

The first is the bearing, although the MV33 motor than the traditional IE3 motor volume is reduced by about 1/3, but the bearing selection can still meet the same bearing model with the same power industrial motor in the market, and is an international first-line brand, in addition, in order to prevent shaft current caused by bearing electrical corrosion problems, 110kW and above models are standard with anti-corrosion design.

Looking at the insulation system, the general low-voltage industrial motor uses a B-level temperature rise design, and the temperature of the whole machine does not exceed 130 degrees. While meeting the B-level temperature rise, the MV33 also has an H-level insulation design with a temperature resistance of up to 180 degrees, and uses a flat wire and an insulation system higher than C-level with a temperature resistance of more than 200 degrees.

There is also the demagnetization problem, in view of the two “culprits” of demagnetization, high temperature and high current, MV33 rotor adopts the design of low temperature rise, and the permanent magnet has done a special treatment, and the standard two temperature sensors are used with the frequency converter, which can receive alarm information in the case of abnormal temperature, and prevent the occurrence of demagnetization problems caused by long-term overload. More importantly, Huichuan has 20 years of experience in the development of permanent magnet motors, with shipments of more than 20 million permanent magnet motors and rich experience in anti-demagnetization design. Under normal operating conditions, the MV33 is not demagnetized.
