Stepper motors resemble servo motors in that both types are characterized by an ability to rotate a partial turn and then stop for any interval with or without holding torque. In addition, both motor ...

A growing number of manufacturers are saving time and money by testing, diagnosing and even repairing servo motors in-house. We look at the expanded role of encoder test systems and present one ...

The primary feature of stepper motors is listed right within their name: their ability to ‘step’ forwards and backwards, something which they (ideally) can do perfectly in sync with the input provided ...

Before choosing between a two-phase or five-phase step motor, take a closer look at the application's requirements and the motor's capabilities. More is not always better, but more phases certainly ...

A new edition of the only American national standard for repair of motors and generators — “ANSI/EASA AR100-2010: Recommended Practice for the Repair of Rotating Electrical Apparatus” (ANSI/EASA AR100 ...

Most stepper motor applications require smooth motion. To achieve extremely smooth movement, some engineers alter the voltage, current, and more often, the microstep ...
