Continuous operation with 100% torque even at low
speed of 3Hz is possible. (when using real sensorless
vector control)
For the 37kW or less, load torque is not need to be
reduced even at a low speed and constant torque (100%
torque) continuous operation is possible within the range
of speed ratio 1/20 (3 to 60Hz). (The characteristic of
motor running at 60Hz or more is that output torque is
constant.)
Installation size is the same as that of the standard motor
Note that operation characteristic in the chart below can
not be obtained if V/F control is employed.
Continuous rated range of use (real sensorless vector control)
Please contact us separately for the motor constants during real sensorless vector control.
When the vector control dedicated motor (SF-V5RU) and inverter are used, the torque characteristics are as shown below.
