For the needs of the FESB electrical machinery laboratory, a model of an electric motor drive with an electronically commutated motor (ECM) was created. The model consists of a 1.5 kW ECM, a diode rectifier, a DC intermediate circuit and an inverter. The motor currents were measured using an LEM sensor and an A/D converter. The following adaptive circuits are required for digital drive control using a TMS 320C50 signal processor: a circuit for processing signals from an incremental encoder, a circuit for generating commutation signals and a timing circuit for generating control signals. The aforementioned circuits were created as part of the diploma thesis, and based on the given control algorithms, a program for controlling the ECM using the aforementioned signal processor was created.
