What does "inverter" mean as opposed to a drive/amplifier which are also used to describe the electronic unit that controls a motor. The terms inverter, drive, and amplifier are used somewhat
interchangeably in industry. But there are subtle differences. A drive can
refer to the motor, the control electronics, or both. This term |
My pump is losing speed; does the drive have a problem? Pumps are divided into three basic categories: centrifugal,
rotary, and reciprocating. Take any of the three types and break it down
further into four parts, the rotating element, the casing, the m |
Can a mechanical motor coupling affect the operation of the drive? Yes, but more as a problem to the entire system including
the drive. Here is a list of Do’s and Don’ts:
DO:
Determine power requirements using both HP and torque to
choose the proper |
Are the variable frequency drives phase sensitive? The input wiring is not sensitive to phase. If one would change one set of input leads, the rotation would not change. The output of the drive is sensitive to phase. Changing one set of leads to the |
My stepper motor is running hot to the touch. Is there something wrong? Stepper motors are designed to run hot. Our Hybrid stepper motors are rated to run in an ambient temperature range of 20 degrees C to 50 degrees C and can have a temperature rise of 80 degrees C. It |
What is a brushless motor? A Brushless DC (BLDC) motor is a rotating electric machine where the stator is a classic three-phase stator like that of an induction motor and the rotor has surface-mounted permanent magnets. In thi |
What is the difference between dual voltage and dual wound motor? Dual voltage is a reference to a motor that can use either of two different voltage levels, usually 230V or 460V. The motor windings have multiple taps, and the connections vary depending on which vo |
