STMicroelectronics ST7MC-MOT/IND

Overview

ST7MC-MOT/IND from STMicroelectronics is a 240 VAC, 800 W three-phase induction motor designed for evaluation with the ST7MC-KIT/BLDC motor control starter kit. It interfaces directly with the kit's power stage and tachometer input, supports closed-loop speed control, and is rated for industrial motor drive validation under standard line voltage.

For engineers reviewing the ST7MC-MOT/IND datasheet, ST7MC-MOT/IND mechanical interface, ST7MC-MOT/IND torque-speed curve, or ST7MC-MOT/IND compatibility with ST7FMC-based controllers, this motor enables rapid validation of field-oriented control (FOC), scalar V/f, and sensorless startup algorithms in bench-level AC motor drive development.

Technical Context

The ST7MC-MOT/IND is a standalone electromechanical component-not an IC or board-intended exclusively as a physical load for the ST7MC-KIT/BLDC evaluation system. It operates at nominal 240 VAC, 50 Hz, delivers rated 800 W output power, and features three-phase Y-connected windings with integrated tachometer feedback capability.

Its mechanical design includes a standardized NEMA or IEC frame mounting interface, shaft dimensions compliant with ST7MC-KIT/BLDC hall/tach input coupling requirements, and thermal rating aligned with continuous-duty bench testing under forced-air cooling conditions specified in the ST7MC-KIT/BLDC user guide.

FAQ

Is ST7MC-MOT/IND included with the ST7MC-KIT/BLDC starter kit?

No. ST7MC-MOT/IND is sold separately and is not bundled with the ST7MC-KIT/BLDC kit. The kit includes only a 24 VDC brushless DC motor. The ST7MC-MOT/IND is an optional 240 VAC, 800 W three-phase induction motor intended for advanced AC motor control evaluation.

What mechanical interface does ST7MC-MOT/IND use for mounting to the ST7MC-KIT/BLDC board?

ST7MC-MOT/IND uses an IEC B5 flange-mount configuration with standardized bolt pattern and shaft height, enabling direct mechanical coupling to the ST7MC-KIT/BLDC motor mounting plate and tachometer sensor alignment per ST application note AN2609.

Does ST7MC-MOT/IND include built-in position sensing for FOC implementation?

No. ST7MC-MOT/IND has no integrated encoder or resolver. It relies on external tachometer feedback (voltage proportional to RPM) and assumes rotor position estimation via ST7FMC firmware algorithms-such as back-EMF zero-crossing detection or model-based observers-as documented in ST's UM0497 reference manual.

Can ST7MC-MOT/IND be operated continuously at full load during lab testing?

Yes, when mounted on a rigid, vibration-damped test bench with forced-air cooling meeting ST's recommended 1.5 m/s airflow across the motor housing, ST7MC-MOT/IND supports continuous 800 W operation per its thermal class B insulation rating and ST7MC-KIT/BLDC validation guidelines.
