This demonstration board implements a 3-phase inverter for low power asynchronous electric motors or permanent magnet AC motors up to 50 W. Nominal input voltage for inverter is 230 VAC - standard single phase connecting. This 3- phase inverter is based on 8-bit ST7FMC motor control controller. Main target of this demonstration board is a very low-cost effective 3-phase inverter for permanent magnet AC motor, but with certain modification of software it can be used also for 3-phase asynchronous motors where high efficiency is required and low cost per solution is a must.
- Possibility to use two motor types:2-phase motor two sinusoidal voltage waves restored with a phase displacement of 90° between them3-phase motor three sinusoidal voltages with phase displacement of 120° among them
- Voltage Input range 115 VAC to 230 VAC 50 Hz or 60 Hz
- High efficiency
- Total output power 50 W
- Compliant with EN61000-6-3 and EN61000-6-2
- Switching PWM frequency 12 - 22 kHz
