The TYC series ultra-ultra-high-efficiency rare earth permanent
magnet synchronous motor that exceeds the IE4 efficiency standard
is the latest special motor for compressors developed by our
company. It adopts high-performance rare earth permanent magnet
materials and frequency conversion technology, operates without
encoder vector control, and has a magnetic steel structure. , has
the advantages of high efficiency, reliable operation, and good
installation interchangeability.
Features:
- Simple and reliable structure: no encoder vector control, can
realize unlimited start and stop.
- High protection level: IP55 protection level avoids the
disadvantages of low protection level motor permanent magnets
absorbing iron dust and blocking the air gap.
- Strong anti-demagnetization ability: It adopts an intercalated
magnetic steel structure and designs a higher maximum
demagnetization working point.
- Good installation interchangeability: the shape and installation
dimensions of the motor are consistent with those of ordinary
asynchronous motors, and the design of the host does not need to be
modified, which is suitable for both new machines and old machines
for energy-saving renovation.
- Ultra-high efficiency operation: Really ultra-high efficiency, the
efficiency is higher than the standard value of IE4 efficiency (the
stray loss is recommended according to the 112B method).
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
temperature rise under the full load service coefficient is
assessed by grade B ( T80K). 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. ln addition to the energy efficiency of IE4, the motors can
better achieve the efficiency of lE5 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.
