3PHBLDCDMM-10-2-A3

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”).
