Product Description:

The PMB33F-10116-03 is the part of PMB Brushless Servomotor series and is manufactured by Pacific Scientific. It provides a rated continuous current of 11 A to provide powerful power output.

The PMB33F-10116-03 brushless servomotor has a rotor inertia value of 0.000404 kgm² that facilitates rapid dynamic response. It is produced in a NEMA 34 frame size that enables it to be used in a standard mounting system. The servomotor incorporates both communication and a 4096 ppr digital encoder to give proper feedback signals. It has a peak torque output of 16.1 Nm that is a guarantee that it can address variations in loads. The servomotor type of round shaft increases the number of drive couplings that it is compatible with. It has a rated operational speed of 4600 rpm that aids high performance motion tasks. The PMB33F-10116-03 brushless servomotor winding design phase resistance of 0.96 ohms is to enhance efficiency in continuous duty. Its phase inductance of 2.8 mH also adds to stable electric performance under different loading conditions. The servomotor allows easy rotation thanks to its viscous damping coefficient of 0.038 Nm/kRPM. It maintains reliable thermal balance with a 32 minute thermal time constant and is safeguarded by a thermal resistance of 0.78 °C/W during long operations. The IP40 protection level guarantees a threshold against solid objects that are bigger than 1 mm.

The PMB33F-10116-03 brushless servomotor weighs are 6.3 kg which facilitates fitting in large scale machines. It has the flexibility of application and choice of options like shaft seal and PTC thermistor. A Coulomb friction coefficient of 0.169 has the least losses and ensures mechanical stability. The 6.3 kg of weight make this motor useful in industrial drive systems.
