Security mechanisms for electric motors and associated systems

A vehicle with a security system, the vehicle comprising:

• a motor having multiple sets of coils;
• a controller electrically coupled to the motor;
• a drive circuitry electrically coupled to the multiple sets of coils;
• and
• a security system having a security unit electrically coupled to the drive circuitry and the multiple sets of coils, the security unit being configured to short-circuit at least one set of the multiple sets of coils responsive to a signal from the controller, wherein the signal indicating that the motor is turned off.

A method for securing a vehicle, comprising:

• receiving, by a controller, a signal regarding turning off the vehicle;
• instructing, by the controller, a security unit to short-circuit a plurality of coils of a motor in the vehicle;
• instructing, by the controller, a circuit controller to send a testing signal verify whether the plurality of coils are short-circuited;
• and
• entering a hibernation mode when receiving a confirmation signal that part or all of the plurality of coils are short-circuited.
