Industrial Technical Article Sinochron® Encoderless Motor
The SINOCHRON® Encoderless Motor design offers advantages in continuous duty applications. The efficiency is also better in partially loaded duty cycles, when compared to standard asynchronous motors. Drive units are virtually loss-free in no-load operation. This motor design offers advantages in powering conveying equipment; escalators, spooling machines, compressors and traction drive units amongst others. By substituting existing line powered three-phase drive units, energy savings of 20 to 35 percent can be expected.
SINOCHRON® is a synchronous motor with high-performance permanent magnets with a sinusoidal flux distribution (EMF). The anisotropic rotor geometry provides a sinusoidal distribution of the magnetic flux with the result of eliminating cogging. Stator windings are identical to asynchronous motor windings allowing for a cost-efficient production of the stators in large batch sizes. The SINOCHRON® Motor operates without an encoder and can replace a stepper motor in some applications. This patented technology combines high output, minimal investment and low operating cost.
The characteristic profile of these drive units makes them well suited to drive pumps and fans that operate continuously, no additional components, like encoders, are needed. Up to 30 percent smaller footprint, allows machine designs to be more compact. The motors have excellent control behavior and combined with included control unit SDC, have excellent true running even at very low speeds and impressive dynamics at impulse load and speed variations.
Continuous duty pumps and fans are now required to meet new efficiency regulations which require line powered three-phase motors and geared-motors with rated outputs of 0.2 up to 9.0 kW operating continuously at rated load (duty cycle S1) to be a minimum of efficiency class IE3 (premium efficiency) or IE2-drive units to be equipped with electronic inverters. Inverter powered SINOCHRON® Motors from ABM Drives economically meet these requirements.
