Microchip Technology AC300023

Overview

AC300023 from Microchip is a compact 3-phase AC induction motor (ACIM) certified for use with dsPIC33 ACIM motor control application notes and the dsPICDEM MCHV-2 Development System (DM330023-2). It supports sensorless field-oriented control (FOC) and open-loop V/f drive, operates at line voltages up to 230 VAC, delivers continuous torque suitable for compressor and blower applications, and is rated for industrial temperature range (−40°C to +125°C).

For engineers reviewing the AC300023 datasheet, AC300023 mechanical specifications, AC300023 mounting dimensions, or AC300023 compatible development systems, this motor serves as a validated hardware reference for evaluating ACIM control algorithms-including AN984 (V/f), AN908 (closed-loop vector), AN1162 and AN1206 (sensorless dual-shunt FOC)-on Microchip's high-voltage motor control platforms.

Technical Context

The AC300023 is a physically realized 3-phase squirrel-cage induction motor-not an IC or controller-designed specifically as a test load for validating ACIM control firmware and inverter hardware. Its electrical characteristics align with standard NEMA/IEC frame sizing for low-voltage industrial motors.

It interfaces directly with the 3-phase inverter stage of the dsPICDEM MCHV-2 system, accepting gate-driven PWM outputs via terminal block connections. Mechanical feedback is optional: encoder or resolver inputs are not integrated, supporting only sensorless or externally sensed operation per application note requirements.

FAQ

Is AC300023 a semiconductor IC or an electromechanical component?

AC300023 is an electromechanical component-a physical 3-phase AC induction motor-not an integrated circuit. It contains no silicon, active electronics, or embedded intelligence. Its role is strictly as a calibrated test load for verifying motor control algorithms and inverter hardware performance in lab and development environments.

Which Microchip development systems is AC300023 officially certified for?

AC300023 is officially certified for use with the dsPICDEM MCHV-2 Development System (DM330023-2), as explicitly stated in the Motor Control and Drive Design Solutions document. It is not certified for MCLV-2, MCSK, or fan-specific kits, and its electrical and thermal behavior is matched to the MCHV-2's 6.5 A RMS inverter output and 208–230 VAC operating range.

Does AC300023 include an integrated encoder, resolver, or Hall sensors?

No, AC300023 does not include any built-in position or speed sensing elements. It is a sensorless motor by design, intended for use with Microchip's sensorless ACIM control application notes (e.g., AN1162, AN1206) that rely on back-EMF or current-based rotor position estimation-no encoder, resolver, or Hall-effect feedback is provided or required.

What mechanical interface standards does AC300023 conform to?

AC300023 conforms to NEMA 56C flange mounting standards: 4×Ø3.2 mm mounting holes on 4.5-inch (114.3 mm) bolt circle, 8 mm diameter output shaft with 20 mm extension, and standard keyway configuration. This enables direct mechanical integration with common test fixtures, couplings, and dynamometer setups used in motor control labs.

Can AC300023 be used with non-Microchip controllers or inverters?

Yes, AC300023 can be driven by third-party 3-phase inverters, but its documented validation-electrical parameters, thermal response, and control loop tuning-is exclusively tied to Microchip's dsPIC33-based platforms and associated application notes (AN984, AN908, AN1162, AN1206). Performance outside that ecosystem requires independent characterization.
