Product Description:
The PMB33C-10100-01 is a brushless servo motor from Pacific Scientific. It features a NEMA 34 frame size and it is built with an exposed-lamination construction for heat dissipation. This motor delivers a continuous steady turn effect of 5.420 Nm under stable load and its peak torque output reaches 16.10 Nm during intermittent operation.
The PMB33C-10100-01 servo motor possess a rated torque of 4.84 Nm at 240V AC input and its normal rotational speed is 1300 rev/min. Its maximum attainable speed is rated at 6000 rev/min and it uses special Neodymium in combination with Iron-Boron magnets for high torque density. The motor operates at 2.90 A and its winding permits peak current of 8.70 A. Its line-to-line resistance is specified at 8.60 Ohms and its inductive value between phases is 27.20 mH for consistent current control. The PMB servo motor generates a torque constant rated at 1.86 Nm for every ampere usage and it produces a back emf of 1.11 Vrms/rad/sec. Its rotor inertia is specified at 0.000404 kg·m² to provide stable load response during acceleration and deceleration cycles. This unit includes a shaft seal as a custom feature for protection against external pollutants. It is accompanied by a round design of shaft that measure 12.7 mm in diameter and for electrical wiring AMP lead is provided on 18” of lead.
The PMB33C-10100-01 servo motor’s frictional torque is limited to 0.169 Nm for smoother operations and it uses a resolver feedback system for closed-loop control. Its thermal resistance is rated at 0.78 °C/watt, while it takes 32 minutes of time to dissipate heat and stable by half the temperature during continuous use. This PMB servo motor includes double-shielded bearings for mechanical endurance and it weighs 13.8 lbs. This model is compatible with PC34xx and SC9xx series drives.
