Torque requirements

A drive sizing makes sure that the drive has enough torque to satisfy the load requirements to overcome friction losses, provide sufficient load thrust, and provide enough acceleration torque for the type of acceleration required. Once the drive-sizing requirement is satisfied, the servo drive stability must be addressed. Stabilizing the servo drive is a matter of adjusting the servo compensation. All industrial servo drives require some form of compensation often referred to as proportional, integral, and differential (PID).

INTRODUCTION In the application of industrial servo drives to machines it is important that the drive be large enough to meet all the load torque requirements and be stable. It is necessary to make sure that the servo drive torque rating is large enough to meet the load thrust and acceleration requirements plus the machine friction losses; an organized method to accomplish this is referred to as ‘‘sizing the drive.’’ There are many drive-sizing software programs available from commercial servo drive suppliers.

One way to solve the single phase problem is to build a 2-phase motor, deriving 2-phase power from single phase. This requires a motor with two windings spaced apart 90o electrical, fed with two phases of current displaced 90o in time. This is called a permanent-split capacitor motor in Figure

DC drives are widely used in applications that require regeneration, precise speed control, dynamic performance, and constant torque over wide speed ranges. The Mentor II delivers the universal DC drive solution. Simple stand-alone applications are easily configured to control motor speed, voltage or current using standard internal settings. Set-up is convenient using the drive keypad, CTKP remote keypad, or MentorSoft, a Windows based drive configuration tool. The Mentor II has extensive diagnostic and communication abilities that enhance system reliability.
