Product Description:
Pacific Scientific manufactures the PMB33C-20100-00 Servomotor for industrial automation systems that requires accuracy and longevity. The motor provides dependable operation during extended duty cycles. The design maintains electrical efficiency under continuous load. The configuration supports accurate positioning in applications demanding controlled motion output.
The PMB33C-20100-00 servomotor has a nominal stall current of 3.8 A. This current rating support continuous electrical supply required to hold torque at zero speed. The motor connection is designed with flying leads equipped with AMP connectors. The connector arrangement allows secure and flexible wiring for integration into electrical systems. The sensor system uses a resolver. The resolver provides robust position feedback and supports control accuracy in harsh operating environments. The construction is rated IP40. The enclosure rating protects against solid intrusion and defines the environmental limits for heavy duty applications. The torque constant is 1.86 Nm per Arms RMS which establishes a predictable relationship between current input and torque output. This value ensures stable control performance. The voltage constant equals 1.11 VRMS per radian per second. The constant defines the back electromotive force attributes across the operating speed range.
The PMB33C-20100-00 brushless servomotor requires a continuous stall current of 2.9 Arms. The continuous current specification determines the energy demand during long-term holding operation. The current at peak torque reaches upto 8.7 Arms. The peak current capability allows short-term overload performance for acceleration or sudden load changes. The resistance measured line-to-line is 8.6 Ohms. The resistance specification defines copper losses and contributes to thermal efficiency. The electrical characteristics support predictable energy consumption under defined duty cycles. The combination of current ratings, resistance and sensor design provides consistent performance within automated motion systems.
