SPECIFICATIONS
8.4 Specification of premium high-efficiency IPM motor
[MM-EFS (1500r/min) series]
Motor specification
*1 The above characteristics apply when the rated AC voltage is input from the inverter. (Refer to page 150.) Output and rated motor speed are not
guaranteed when the power supply voltage drops.
*2 This excludes the part where the axis passes through.

REMARKS
· The motor can also be used for applications which require the rated speed of 1800r/min.
CAUTION
• The torque characteristic is when the armature winding temperature is 20°C, and the input voltage to the inverter is
400VAC.
• Constant-speed operation cannot be performed for the speed of 150r/min or less.
