Product Description:
The Pacific Scientific PMB33F-20116-03 is a premium brushless servomotor from the PMB series designed for applications needing accurate motion control and efficient output.
The signal input/output is housed in a NEMA size 34 frame with three distinct stack lengths in order to save design space without compromising functionality. Flying leads and AMP connections may be used to securely electrically integrate the motor and make it compatible with a variety of automation devices. This motor's digital encoder with commutation offers accurate position feedback and a responsive, fluid machine with an accuracy of 4096 pulses per revolution. The nominal stall current of the motor is 11.0 ARMS. It provides a steady stall torque of 5.42 Nm (48.0 lb-in), which sets its performance limits and gives reliable operation under full load conditions. The highest torque it can produce in high-demand, short-term situations is 16.1 Nm (142 lb-in). Because of its typical speed rating range of 1300–4600 RPM, it may be used in both high-torque and increasing-speed applications.
At 0.404 × 10⁻³ kg·m² (3.57 × 10⁻³ lb-in·s²), its rotor inertia offers a good mix of rapid acceleration and low vibration. The viscous damping coefficient (0.038 Nm/kRPM, or 0.34 lb-in/kRPM) and low static friction of 0.169 Nm (1.50 lb-in) assist the mechanical performance, maintaining stability in a range of operating conditions. The motor is thermally resistant with 0.78 °C per watt, which promotes heat dissipation. It also consists of a thermal time constant of 32 minutes, which can easily maintain a steady temperature under full load. The motor is simple to integrate due to its robust mechanical structure and 6.3 kg (13.8 lbs) weight. It can be purchased at Wake Industrial with a one-year warranty.
