NEMA-42 (D-Type) way seems promising.. in any of following two ways; NEMA-42 can hold without falling back...
I just need to keep it ENERGIZED i.e. power and backup power present.. the holding and locking it will provide is called HOLDING TORQUE.
Detent torque and holding torque
One feature of stepper motors that differentiates them from other motor types--particularly servo motors--is that they exhibit holding torque. This means that when the windings are energized but the rotor is stationary, the motor can hold the load in place. But a stepper motor can also hold a load in place when there is no current applied to the windings (for example, in a power-off condition). This is commonly known as the detent torque or residual torque.
