ADVANCED Motion Controls announces micro sized Z-Drives

June 4, 2015 -  ADVANCED Motion Controls announces AZBH10A4 and AZBD10A4 analog plug-in brushless servo drives that handle brushless and brushed DC motors at a high switching frequency.

To increase system reliability and to reduce cabling costs, the drives are designed for direct integration into a PCB. Weighing in at just 9 grams, these drives output 10A peak and 5A continuous and operate with a bus voltage range of 10-36VDC.

Designed without the need for a heatsink, they are fully protected against over-voltage, under-voltage, over-current, over-heating, and short-circuits.  Depending on the model, the drives interface with digital controllers that have analog ±10V or PWM/Direction commands. These servo drives require only a single unregulated isolated DC power supply, and are fully RoHS (Reduction of Hazardous Substances) compliant.

The AZBH10A4 with Hall Velocity mode uses the motor's commutation sensors for velocity feedback.  This cost-effective control scheme is suited for medium to high speed applications where it provides excellent velocity control performance. Hall Velocity mode is ideal for velocity controlled conveyors, pumps, fans, and anywhere velocity control is needed.

The AZBD10A4 with Duty Cycle mode estimates velocity based on the PWM duty cycle to provide a limited level of velocity control without the need for a velocity feedback device such as an encoder. This control scheme is used in simple applications where velocity feedback is not available and precise velocity control is not necessary such as in some drive wheel applications, fans, pumps and lifts.

Both models each have a loop gain potentiometer used to tune the responsiveness, and an offset potentiometer to correct for any imbalances.  Onboard jumpers control the inhibit logic, commutation phasing and feedback polarity.
