Rotation ripple at low speed
What are rotation ripples (%) at low speeds, in concrete, at 2 r/min, 20 r/min, and 200 r/min?
- Category :
Answer
The rotation ripple data for 1.5 kW is shown below.
Drive unit: MD-CX520-1.5K
Motor: MM-CF152
Load: None (motor alone), carrier frequency: 2 kHz, wiring length: 1 m, surrounding air temperature: room temperature
Rotations per minute: Rotation ripple (wow flutter rate (%))
* Wow flutter rate = Rotation ripple (P-0)/Average rotations per minute × 100 (%)
2 r/min: No rotation
20 r/min: No rotation
100 r/min: Approximately 2.3%
120 r/min: Approximately 1.0%
140 r/min: Approximately 0.4%
160 r/min: Approximately 0.3%
180 r/min: Approximately 0.1%
200 r/min: 0.0%
