AC Motors offer encoder-free motion control with zero slip.
May 13, 2008 -
Rated 0.25-10 kW, SINOCHRON® motors are enclosed in aluminum housing and use 3-phase stator winding with rotor having permanent magnets embedded in stack. This produces sinusoidal magnetic field and even flux distribution in motor, resulting in smooth, constant-speed operation, independent of load, with no torque ripple. Exceeding EPACT 1 efficiency in fractional sizes, motors exhibit typical accuracy under 1° when coupled to gearbox or ±5° at motor shaft.
New SINOCHRON® AC Motors Offer Encoder-Free Motion Control With Zero Slip and Overspeed Capability
Exceeds EPACT 1 efficiency in fractional sizes. Packs same torque into frame size one smaller than standard motors due to exceptionally high power-density design.
May 2008 - ABM DRIVES INC. introduces encoder-free motion control with its new line of zero-slip, high-efficiency SINOCHRON® motors rated at 0.25-10 kW. SINOCHRON® motors save initial cost, energy and space, while improving reliability. They eliminate the need for an encoder in medium accuracy applications, and produce torque equal to the next larger frame size of a standard AC motor. SINOCHRON® motors exceed EPACT 1 efficiency in fractional horsepower sizes, delivering 25-40% higher efficiency, depending on the operating range. They can be used for a wide range of medium-dynamic, medium-accuracy applications, such as stair/car/truck lifts, crane drives, powder-coating machines, packaging machines, industrial doors and hydraulic pumps.
"SINOCHRON® motors bridge the gap between standard AC motors with low dynamic and no position feedback, and servo motors with high-dynamic and high-accuracy," said Heiko Doehler, senior application engineer for ABM DRIVES INC. "SINOCHRON® motors have a much higher dynamic than standard AC motors, though less than a servo, with motion-control accuracy that's about 98 percent that of a servo. They are ideal for many applications where a servo motor is overkill technology."
Totally enclosed in an aluminum housing, SINOCHRON® motors use a standard 3-phase stator winding with a custom-designed rotor having permanent magnets embedded in the stack. This produces a perfectly sinusoidal magnetic field and even flux distribution in the motor, resulting in smooth, constant-speed operation - independent of load - with no torque ripple. The perfectly sinusoidal back-EMF signal from the motor allows SDC's (sensorless drive controllers) to calculate speed and position without an encoder, eliminating the cost, reliability and additional wiring issues for an encoder. Typical accuracy can be under 1° when coupled to a gearbox, or ±5° at the motor shaft.
High-efficiency SINOCHRON® motors are ideal for use in battery powered traction and steering applications or as a low-cost alternative to servos in medium-dynamic applications. The embedded permanent-magnet design produces a higher dynamic than a standard AC motor for faster response/acceleration with better speed control. It also allows field weakening for overspeed use at reduced output torque, while the high efficiency delivers longer battery life between charges.
SINOCHRON® motors are sealed to IP 65, and compliant with CE, UL, DIN EN 61800-3 and RoHS. Numerous hardware and software options are available, including gearboxes, brakes, connectors, etc.
