MT30R4-37 SEM D.C. Servomotors

■ Motor Performance data is on the basis of a pure D.C. i.e. unity system form factor supply.
Appropriate performance derating is necessary when using a supply with a system form factor
greater than unity.
■ Commutation Curves opposite and peak torque are based on the peak value of the current
wave form. For a form factor greater than unity the maximum torque permitted will be lower than
that detailed on the performance curves. IMPORTANT The commutation curves are based on a
load inertia equal to the motor inertia. Advice should be taken in the event the load inertia is
greater than the motor inertia.
● Heatsink Ratings Torque ratings shown in brackets (opposite top right) are correct for motors
when fitted to a heatsink size (300mm x 300mm x 12mm)
