Overview
A stepper motor (or step motor) is a brushless, electric motor that can divide a full rotation into a large number of steps. The motor's position can be controlled precisely without any feedback mechanism (see Open-loop controller), as long as the motor is carefully sized to the application.
Lifetime
The typical lifetime for a stepper motor is 10,000 operating hours. This approximates to 4.8 years; given the stepper motor operates one eight-hour shift per day. The lifetime of a stepper motor may vary in regards to user application and how rigorous the stepper motor is run.[1]

Torque Tests
Test 1
This test used Nema17 stepper motors driven by A4988 driver boards http://reprap.org/wiki/Stepper_torque
Summary: All motors perform well at speeds < 100 revs/min. Dynamical torque starts to drop off at speeds higher than 300 rev/min. The higher the rated current and the lower the inductance, the better the performance at high speeds.
