Permanent Magnet Motor Product Description:
This series of motors is specially designed to consider the special
working conditions of the compressor, with high efficiency, low
noise, strong overload capacity, long bearing life, and so on. The
performance and installation size of this series of motors conforms
to the lEC60034 standard, DIN42673 standard, GB755 standard, and
related professional and technical standards. And the company has
passed IS09001 international quality system certification many
times.
From the order, development, manufacturing, inspection, sales, and
service process in accordance with the requirements of IS09001
quality system control. This series of motors consider that the
cable of the motor is directly connected to the electric control
box of the compressor. According to the user's requirements, the
motor can be equipped with extended lead wire and screw sleeve;
This series of motors features a rotor with a permanent magnet.
This technology offers significant advantages to the motor, such as
higher efficiency, power factor, and higher power density.
They are driven by frequency converters that provide constant
torque over a wide range of speed changes and operate even at low
speeds with higher efficiency than induction motors. In addition to
the energy efficiency of IE4, the motors can better achieve the
efficiency of IE5 on the market today.
Demonstration of advantages:
1. Greater power density - reduced mass and volume
Permanent magnets inserted into the rotor ensure a considerable
reduction in electrical losses, thereby reducing the motor
temperature and making it possible to use a smaller housing size.
The mass and volume of an equivalent motor are reduced by 70%
compared to an induct motor with the same output power and speed.
The shaft and bearings of the motor can withstand higher power and
torque in a smaller housing size.
2. The motor provides superior efficiency at a full range of speeds
or loads
The motor offers excellent efficiency regardless of speed or load,
saving up to 30% of energy compared to inverter-driven induction
motors.
3. Maintain constant torque in a wide range of speed regulation
The motor can operate with constant torque over a wide speed range.
This feature makes it ideal for applications that require speed
variations and constant torque, even at low speeds, without the
need for an encoder. The motor is able to operate at up to 30%
higher than its rated speed without the use of special components.
4. Permanent magnets
Electric motors use powerful permanent magnets. These magnets are a
combination of neodymium, iron, and boron (NdFeB), commonly known
as rare-earth magnets. They are 18 times stronger than traditional
ferromagnets. To provide excellent mechanical strength and
corrosion resistance.NdFeB magnets are covered with a protective
epoxy resin coating
5. Thermal protection device
Motor windings built-in PTC(positive temperature
coefficient)thermistor, or PT100 platinum thermistor, can provide
comprehensive protection against overheating due to lack of phase,
overload, and under voltage or overvoltage.
6. Bearing life up to 100,000 hours
The motor is equipped with bearings that can provide up to 100,000
hours of L10 life. All motors are equipped with open bearings and
endcaps with refueling nozzles that allow for re-lubrication, thus
reducing downtime for maintenance.
7. Universal features:
A strong and versatile foot makes motor calibration and
installation easier. The rigid cast iron construction provides high
mechanical strength and low vibration ratings. The fully enclosed
structure can be used in a variety of harsh working conditions. it
can be used with inverters from many manufacturers at home and
abroad.
