Overview
Wide-speed IPMSM drive with field-oriented control, MTPA, field weakening, and space-vector PWM.
This example demonstrates wide-speed operation of a 50 kW IPMSM drive using field-oriented control with maximum torque per ampere and field-weakening strategies. It is a strong transportation and electric-drive seed post.
The model includes a 550 V DC bus, a two-level three-phase converter, an IPMSM machine, and an FOC controller with d-q current regulation, speed control, torque limiting, MTPA, and field weakening.
This post expands the initial content beyond grid studies into mobility and industrial drives. It also aligns well with transportation-focused community segments and motor-control discussions.
Key Features
- Wide-speed operation including overspeed region
- MTPA optimization for lower current magnitude
- Field weakening for high-speed operation
- Generator-mode operation in one of the test cases
- Space-vector PWM at 8 kHz
Getting Started
- Choose one of the built-in tests and run the simulation.
- Compare normal-speed and overspeed behavior.
- Observe the effect of disabling MTPA on current magnitude and losses.
- Run the wide-speed test to explore field-weakening behavior.
