The modernized three-phase brushless DC drive module (hereinafter - 3PHBLDCDMM or module) is intended for three-phase electric AC motor controlling on constant magnets with rotor position converter. 3PHBLDCDMM is performed on the basis of modern power electronics, microelectronics, digital-to-analogue integrated circuits and controllers of digital and analogue signal processing with the integral PWM schemes.
3PHBLDCDMM supports the following functions and performances:
- Controllable start/stop of engine;
- Motor shaft rotation direction change;
- Rate control;
- Speed hold when change of motor supply voltage;
- Electric motor protection against current overload and short-circuit;
- Protection against pulse current surges;
- Current protection pickup setting;
- Overheating protection;
- Protection against simultaneous turn-on of top and lower inverter arm transistors;
- Protection against incorrect combination of signals from rotor position transducer;
- External signaling about an accident;
- Internal voltage control;
- Module power from the power circuit;
- Allows supplying the external circuits with its own stabilized voltage +5 V and +15 V with protection against current overload;
- Connection of AC voltage without rectification (3PHBLDCDMM with radiator type “3”);
- Smooth charge of filter capacity without additional charge resistor and charge control circuits (3PHBLDCDMM with radiator type “3”).
