Product Description:

The company Pacific Scientific produced the PMB33C-10116-02 Servo Motor for precision motion control tasks in industrial automation. It uses an eight-pole motor design for stable torque generation. It comes in a NEMA Size 34 housing suitable for standard installation. The overall motor length is about 210.3 millimeters.

The PMB33C-10116-02 servo motor shaft is a rounded and smooth type that allows easy coupling to mechanical systems. The optional seal kits are available to support different application needs. The motor provides continuous torque of 4.8 or 5 Nm and also delivers a peak stall torque of 9.7 or 15.9 Nm, depending on the matched drive. The motor includes stack length variations to tailor torque output to application needs. The PMB33C-10116-02 servo motor supports an electrical bus of 240 V AC or 320 V DC. The winding configuration allows a stall current of 3.8 A. The rotor inertia is measured at 0.40 × 10⁻³ kgm² with an encoder. The inductance line-to-line value is 27.2 mH. The thermal stability is maintained with Class F insulation. The bearings with double shielding can accommodate radial and axial stresses together. The digital encoder functions as the primary sensor with commutation features.

The PMB33C-10116-02 servo motor supports a nominal speed of about 1900 rpm when operated with compatible drives. The encoder resolution is 4096 pulses per revolution. The encoder channels include quadrature signals and an index reference. The feedback system also includes commutation tracks for drive synchronization. A flying lead wiring setup with AMP mini Mate-N-Lock connectors is used in the motor. The environmental protection is rated as IP40. The operating ambient temperature is near 40°C for rated performance. The insulation is safeguarded when operating under non-condensing humidity conditions.
