Encoder for Brushless Motors rolled out today

Tag: Brushless Hub Motor

Dynapar announces the introduction of the HC20, a commutation encoder priced over forty percent lower than previous models, designed for use in brushless servo and step motor applications. Unlike some other encoders in this price range, the HC20 features direct-read non-interpolated technology that stems from a custom phased array ASIC, and is available with a wide 5-26VDC operating range. In addition, the high 120 degrees C temperature rating won't limit motor performance, allowing manufacturers to keep from de-rating torque specs. The encoder is capable of up to 2500PPR (pulses per revolution) and is available with commutation tracks for 4, 6, or 8 pole variants of brushless motors.

Compact Design

The space-saving design of the phased array ASIC allows for compact dimensions on the HC20. With an industry-standard 50mm diameter and short 36mm mounting depth, the encoder is perfectly suited for use on NEMA 23 and 34 size brushless servo and stepper motors. The compact dimensions allow its use inside standard motor endbells, saving the motor manufacturer from costly redesign.

Simplified Mounting Options

With multiple shaft sizes and tether options, the HC20 can be used with a variety of motors. The choice of 6mm or 8mm hollow or hub shaft options is standard, as is a 9mm shaft with 10:1 taper. Two tether options are also offered, in 40mm and 55mm bolt circles. The mounting holes are crescent-shaped, allowing rotation of the encoder body to help with alignment of the commutation channels with rotor position.

Economical Choice for High Volume Motor OEM's

The HC20 commutation encoder is built to order and immediately available for the general market. Dynapar will market the encoder under the Dynapar(TM) brand name, and list pricing starts at $95. For custom OEM applications and volume pricing, contact a Dynapar representative at 800-873-8731 or visit the web at www.dynapar.com/ServoSolver.
