Specification of high-efficiency IPM
motor [MM-EF (1800r/min) series]
8.5 Specification of high-efficiency IPM motor
[MM-EF (1800r/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.

or 400VAC.
• Constant-speed operation cannot be performed for the speed of 180r/min or less.
