Market Research

The demand for micro-mobility devices such as e-scooters and e-bikes is on the rise. This can be explained by multiple factors including an increased need for fuel-efficient vehicles due to concerns over carbon and greenhouse gas emissions, increasing adoption of electric scooter sharing services and the “pandemic effect” as more people explore options of individual, socially-distanced travel with micro-mobility devices over public transportation. The global e-scooter market is expected to grow from $20 to $42 billion from 2020 to 2030 according to Grand View Research. To capture additional market share of this growing market, e-scooter OEMs must develop smaller, more efficient and higher-performance designs.

Design Challenges:

  • Competitive cost
  • Limited battery size
  • Low operating acoustic noise
  • Regenerative braking capability

Other Reference Designs

Air Conditioner Reference Design

Our Air Conditioner Reference Design, based on the dual-core dsPIC33CH family of Digital Signal Controllers (DSCs), demonstrates efficient control of the condenser fan, compressor, PFC and the overall application logic implementation. The high-performance dsPIC33C DSCs offer the right set of peripherals for dual-motor control and reduce the need for three controllers down to one for cost and space savings in your design.

Refrigerator Compressor Reference Design

This dsPIC33 motor control DSC-based refrigerator compressor reference design will help you rapidly prototype and develop a cost-effective design. The design works with a wide variety of refrigerator compressor PMSM motors and implements sensorless control and a single-shunt current sensing technique to save BOM cost. It also addresses the challenges of maintaining reliable startup of the compressor when faced with high pressure and low standby power consumption

Low-Power High-Voltage Motor Control Reference Design

This high-voltage reference design board is targeted to control AC Induction Motors (ACIMs), Permanent Magnet Synchronous Motors (PMSMs) and Brushless DC (BLDC) motors in sensored or sensorless operations. The board is designed to demonstrate the capabilities and efficiency of high-voltage motor control operations at a low power of up to 150W.

Software Tools

motorBench® Development Suite

The motorBench Development Suite is a Graphical User Interface (GUI)-based software development tool for Field Oriented Control (FOC), performing accurate measurement of critical motor parameters, automatic tuning of feedback control gains and generating source code for an MPLAB® X IDE project utilizing the Motor Control Application Framework (MCAF). 

Motor Control Modeling and Simulation

We offer a rapid prototyping solution that allows compiling and flashing a Simulink® model of a motor control system into a dsPIC® DSC with a single push of a button. The Simulink blocksets and models are supported by our devices and development boards for a complete hardware and software motor control solution to make prototyping your next motor control design easier.

Motor Control Library

The Motor Control Library contains function blocks that are optimized for the dsPIC33 families of Digital Signal Controllers (DSCs). All functions in this Motor Control library have input(s) and output(s), but do not access any of the DSC peripherals, making the library modular to use across the dsPIC33 families.

MPLAB® Mindi™ Analog Simulator

MPLAB Mindi Analog Simulator uses a SIMetrix/SIMPLIS environment to model circuit behavior. reducing design time with software debugging for initial design verification
