1Add 5 % error when selecting Motor design type Other
Specification valid for Motor Power > 30 % of rated power
Specification valid at stable operating temperature. Run the motor for at least 1 hour at full load
(2-3 hours if the motor is 50 HP or higher) to obtain stable temperature.
Notes:
• Supports motor design types NEMA A, B, C, D & E and IEC type H and N.
• Rated torque is calculated from rated power and rated speed.
• Update rate of Motor Measurements
