Product Definitions
DMK: Development and Motor Kit
The DMK (Drive Measurement Kit) is a compact measurement instrument for inverter-driven motors. It measures phase currents and PWM voltages and synchronizes them to rotor position, providing real-time visualization and data logging. It replaces oscilloscope, current probes, data logger, and PWM monitoring equipment in motor test setups. Key features: real-time display, portable form factor, USB-C, WiFi, Ethernet, galvanic isolation.
LCI: Low-Cost Inverter
The LCI is a production-ready, cost-optimized inverter platform for permanent-magnet synchronous motors (PMSM). It combines sensorless field-oriented control (FOC) software with flexible inverter hardware templates. It is designed for high-volume applications such as household appliances, power tools, pumps, and e-bikes, reducing system cost by eliminating position sensors.
AMC: Appcon Motor Control
AMC (Appcon Motor Control) is a software-only sensorless motor control solution that can replace a position sensor in drive control applications. It computes motor speed and position and integrates into existing drive software with minimal changes. It supports PMSM, BLDC, and induction motors and is validated in simulation (SiL) for production use.
Technical Concepts and Specifications
- Field-Oriented Control (FOC)
- A method of controlling AC motors by transforming stator currents into a rotating reference frame aligned with the rotor flux. FOC enables precise torque and speed control and is used in sensored and sensorless implementations.
- Sensorless motor control
- Motor control that does not use a physical position or speed sensor (e.g. encoder, resolver). Position and speed are estimated from electrical quantities (currents, voltages) using observer algorithms.
- PMSM (Permanent Magnet Synchronous Motor)
- An AC motor with permanent magnets on the rotor. Often used in applications requiring high efficiency and torque density, including appliances, tools, and electric vehicles.
- BLDC (Brushless DC motor)
- A permanent-magnet motor driven by DC (or trapezoidal) currents. Often used interchangeably with PMSM in industry; control can be trapezoidal or FOC.
- Inverter
- Power electronics that convert DC to AC to drive an electric motor. Typically a three-phase bridge with MOSFETs or IGBTs and gate drivers.
- SiL (Software-in-the-Loop)
- Validation of control software in simulation before deployment on hardware. AMC is SiL-validated for production readiness.
