Abstract

A gun control unit for a M134 minigun firearm including an armature and a stator comprising at least one hardware processor; and one or more software modules that are configured to, when executed by the at least one hardware processor, independently control the armature; independently control the stator.

Claims (25)

1. An M134 minigun firearm gun control unit (GCU) configured for use with an M134 minigun firearm, the M134 minigun firearm including an electric motor, the GCU comprising:

at least one hardware processor;

one or more software modules are configured to, when executed by the at least one hardware processor, control the speed of the electric motor by controlling the duty cycle of DC voltage to the electric motor.

2. The GCU of claim 1 , wherein the M134 minigun firearm includes an armature and a stator, and the one or more software modules are configured to, when executed by the at least one hardware processor, independently control the armature; independently control the stator.

3. The GCU of claim 2 , wherein the GCU includes one or more solid state metal-oxide-semiconductor field-effect transistors (MOSFETs).

4. The GCU of claim 2 , further including one or more feedback sensors, and the one or more software modules are configured to, when executed by the at least one hardware processor, receive one or more feedback signals from the one or more feedback sensors and provide closed loop control of the armature and the stator based on the received one or more feedback signals from the one or more feedback sensors.

5. The GCU of claim 4 , wherein the one or more feedback sensors include a speed sensor.

6. The GCU of claim 4 , wherein the one or more feedback sensors include an accelerometer sensor.

7. The GCU of claim 4 , wherein the one or more feedback sensors include a temperature.

8. The GCU of claim 4 , wherein the one or more feedback sensors include a speed sensor, an accelerometer sensor, and a temperature sensor.

9. The GCU of claim 1 , wherein the M134 minigun firearm includes a solenoid, and the one or more software modules are configured to, when executed by the at least one hardware processor, independently control the solenoid.

10. The GCU of claim 1 , wherein the one or more software modules are configured to, when executed by the at least one hardware processor, send control signals in a pulse width modulation (PWM) format.

11. The GCU of claim 1 , wherein the electric motor is a three-phase brushless (BLDC) electric motor and further including hall effect sensors, and the one or more software modules are configured to, when executed by the at least one hardware processor, control the three-phase BLDC electric motor for each phase, decreasing generated heat in the M134 minigun firearm.

12. The GCU of claim 11 , wherein the GCU includes one or more solid state metal-oxide-semiconductor field-effect transistors (MOSFETs).

13. The GCU of claim 11 , wherein the GCU is configured to be manufactured with the rest of the M134 firearm.

14. The GCU of claim 11 , wherein the GCU is configured to replace a two relay GCU including a first relay to control the armature and the stator, and a second relay to control the solenoid.

15. The GCU of claim 1 , wherein the M134 minigun firearm includes a handle grip with hall-effect switches to control motor speed.

16. The GCU of claim 1 , wherein the M134 minigun firearm includes a LCD configured to allow a user to monitor one or more different sensors and one or more different actuators.

17. The GCU of claim 1 , wherein the M134 minigun firearm includes a LCD configured to allow a user to monitor one or more of number of rounds, speed, temperature, vibration, status of battery, wireless/satellite communication, GPS, view documents, and view history of events.

18. The GCU of claim 1 , wherein the M134 minigun firearm includes a LCD configured to allow a user to save settings such as a predefined number of rounds, Max and Minimum speed, and enable an e-fence feature.

19. The GCU of claim 1 , wherein the M134 minigun firearm includes a LCD having a capacitive or resistive touch screen to control different functions.

20. The GCU of claim 1 , wherein the M134 minigun firearm includes a plurality of external pushbuttons to control different functions.

21. A method of retrofitting a M134 firearm, comprising

removing from the M134 firearm the two relay GCU including the first relay to control the armature and the stator, and the second relay to control the solenoid;

replacing the two relay GCU of the M134 firearm with the GCU of claim 1 .
