Product Description:
The PMB33E-20116-02 made by Pacific Scientific is a high-performance brushless servo motor of the PMB series with high performance and precision.
It features a NEMA Size 34 frame design and so has a standardized and compact setback. The motor has flying leads with AMP connectors for simple electrical mating into automation systems. The digital encoder has commutation and a resolution of 4096 pulses per revolution, and so the motor provides a smooth performance with accurate position feedback. The PMB33E-20116-02 achieves a continuous torque of 5.4 Nm (48.0lb-in) and a peak torque of 11.0Nm (97.4lb-in) with a multiple of 3 stack length, which means that it will be useful both with high sustained loads and also high-duty applications that only last a short time. The motor is adjusted and set to run at 2900 RPM, which is its maximum rating using a 240 V AC power system. It can also operate a 320 V DC bus, making it more flexible and cost-effective in industrial applications.
The nominal stall current and maximum winding current are both 7.4 ARMS, with a torque constant that is designed to produce efficient generation of torque per unit of current. The value of the rotor inertia is 0.40 kg·cm² (3.57 lb·in²), which provides a compromise between rapid acceleration and controlled movement performance. The line-to-line resistance of the motor is 1.4 Ω, which facilitates the sustainable electrical performance of the motor. It also contains 6.8 mH of inductance that leads to smooth functionality and effective consumption of power. With a weight of 6.8 kg, the motor is constructed to provide strength and long-lasting qualities in an industrial setting. It can be used in automation, robotics, and manufacturing applications, with precise, repeatable performance being the desired feature.
