Research delivers a dozen drives tips

Respondents of the motors and drives survey from Control Engineering give 12 tips related to motor drives. Online see more advice.

10/14/2017


Advice for use of motor drives was included among in the responses to the Control Engineering motor drive research study. Respondents were asked what advice they would offer about motors and drives. Advice on drives included energy efficiency, integration, communications, and programming. 

1. Stamping presses and metal forming require careful ac drive selection, sometimes with regeneration and energy absorbing capacity.

2. Variable speed drives help clarify speed and torque curves.

3. Save money in applications by selecting separate, task-specific low-cost drives rather than all-in-one drives.

4. Use the safety interlocks feature, which is the ability to put a drive into a no-torque condition while remaining powered.

5. Select the right type of variable frequency drive (VFD) to fit the rotating equipment and operational load variations to achieve maximum power consumption reduction over time. Choose a VFD for longer availability.

6. When selecting a drive, a service back-up is important.

7. The fully integrated cost of a drive is much more important than just the cost of the drive.

8. Use care in applying active front end drives on typical commercial building applications.

9. Consider cable shielding and grounding, especially for medium-voltage (MV) drive applications.

10. Harmonics and power quality affect the motor and power system.

11. Don't go for all of the bells and whistles. Basic drives do the same job and offer easier programming and troubleshooting.

12. Use drives to save energy.
