STMicroelectronics STEVAL-SPIMD20V1

Overview

STEVAL-SPIMD20V1 from STMicroelectronics is a demonstration kit built around the SPIMD20 integrated 2 kW brushless motor drive, featuring real-time connectivity, a shuttle module, junction tower for motor mounting, adapter board, cables, software package, and documentation. It enables rapid evaluation of motion control system performance in industrial automation and electric actuator development.

For engineers reviewing the STEVAL-SPIMD20V1 datasheet, STEVAL-SPIMD20V1 pinout, STEVAL-SPIMD20V1 application, or STEVAL-SPIMD20V1 equivalent, this kit supports functional validation of SPIMD20-based motor control firmware, interface timing verification (RS232, analog I/O), thermal behavior under load, and mechanical integration with BLDC motors up to 2 kW.

Technical Context

The STEVAL-SPIMD20V1 implements a complete hardware-software evaluation platform for the SPIMD20 - a fully integrated motor drive IC combining gate drivers, power MOSFETs, current sensing, protection circuitry, and digital control interface. It supports real-time command input via RS232 and analog voltage signals for speed/torque control.

Designed jointly by STMicroelectronics and ROBOX S.p.A., the kit includes a junction tower (AS3036.001) with standardized mechanical mounting and connectorized I/O (CAVO1SPIMD/RS232/1.5, CAVO2SPIMD/2.5/2), enabling repeatable integration into test benches and prototype motion systems.

FAQ

What is the maximum motor power supported by the STEVAL-SPIMD20V1?

The STEVAL-SPIMD20V1 is rated for continuous 2 kW motor output using the SPIMD20 shuttle module. This rating assumes adequate heatsinking and ambient temperature ≤40 °C. Peak power may exceed 2 kW briefly during acceleration, but sustained operation above 2 kW requires external thermal management per the SPIMD20 datasheet limits.

Does the kit include software for configuring the SPIMD20 drive?

Yes, the STEVAL-SPIMD20V1 includes a dedicated software package supporting real-time parameter configuration (e.g., current limit, speed ramp, PWM frequency), waveform visualization of motor phase currents and voltages, and fault event logging via the RS232 interface. No additional license or compiler is required for basic operation.

Can the STEVAL-SPIMD20V1 be used with motors other than those supplied by ROBOX?

Yes - the kit uses standard three-phase motor connections and supports any surface-mounted or interior permanent magnet BLDC motor with compatible voltage/current ratings (≤200 V DC bus, ≤20 A RMS phase current). Mechanical mounting relies on the AS3036.001 junction tower's universal flange pattern, not proprietary motor interfaces.

Is the RS232 interface isolated on the STEVAL-SPIMD20V1 board?

No, the RS232 interface on the STEVAL-SPIMD20V1 is non-isolated and shares ground with the SPIMD20 power stage. For noise-sensitive environments or multi-unit synchronization, external isolation (e.g., ADM2483-based level-shifting transceiver) is recommended between the host PC and the kit's CAVO1SPIMD/RS232/1.5 connector.
