Degree: "0.9 Degree" refers to the step angle of the stepper motor. It indicates the angular increment per step that the motor takes when receiving a command.

Phase: "2 Phase" means that the motor has two separate windings, also known as phases, which are energized in a specific sequence to make the motor rotate.

Voltage: "5.45V DC" represents the recommended or rated voltage for operating the stepper motor. This is the voltage that should be applied to the motor for optimal performance.

Size: "424260mm" indicates the physical dimensions of the motor. The NEMA 17 standard specifies a flange size of 42mm by 42mm, but the height dimension of 60mm suggests that this particular motor may be slightly longer than the standard NEMA 17 size.

Holding Torque: "600mN.m" represents the holding torque of the motor. Holding torque is the amount of torque the motor can generate to maintain its position when no external force is applied. In this case, the motor has a holding torque of 600 milliNewton-meters.
