Product Description:
The PMB31D-00214-00 is a brushless servomotor from Pacific Scientific’s PMB series. It features a NEMA 34 frame size and it measures 134.1 mm in length, while its front mounting face is 87.4 mm to accommodate mechanical interfaces. This motor has flat shaft configuration and its housing is rated IP40 that permits usage only in protected industrial settings.
The PMB31D-00214-00 motor possess MS-type connecting leads for both feedback and power connection. Its power cable is 457 mm long, shielded and uses 18 AWG conductors while the feedback cable is also 457 mm, shielded and uses 26 AWG conductors. This motor is naturally convection-cooled but supports base mounting to a heatsink of dimension 10 x 10 x 1/4 inches to improve thermal rating. Its feedback device is a digital encoder that provides accurate motion control through its 2048 ppr resolution. The PMB31D motor provides 2.11 Nm of continuous stall torque and it delivers up to 6.26 Nm of peak torque for intermittent loads. Its typical speed is 6000 RPM at the operating voltage of 240 VAC and the rotor inertia with the encoder measures 0.000137 kg·m², to tackle high speed operations with control. The motor has a torque constant of 0.41 Nm/Arms and it produces a back emf of 0.25 V/krpm.
The PMB31D-00214-00 motor’s impedance between two line is measured as 2 Ohms and its inductive value stands at 5.2 mH. It uses a steady current of 5.1 A and its peak full load current reaches up to 15.3 A. The unit possess a static friction of 0.09 Nm and its damping factor has a rated value of 0.0124 Nm/krpm. It takes 28 minutes to cool down during operations and it offers a thermal impedance of 1.08 °C/W to dissipate heat efficiently.
Frequently Asked Questions about PMB31D-00214-00:
Q: What is the purpose of the 2048 ppr encoder in the PMB31D-00214-00 motor?
A: The 2048 pulses per revolution (ppr) encoder provides fine position feedback for precise closed-loop motion control. This enhances accuracy during high-speed operations.
Q: Why is a flat shaft used in the PMB31D-00214-00 motor?
A: A flat shaft allows better mechanical coupling and prevents slippage in high torque applications. It improves connection reliability with couplings or gears.
Q: How does the thermal impedance of 1.08 °C/W benefit the PMB31D-00214-00 motor?
A: It enables the motor to dissipate heat effectively, maintaining operational stability. This is particularly crucial when the motor runs near peak current loads.
Q: How does the damping factor of 0.0124 Nm/krpm affect performance?
A: It helps reduce oscillations and vibrations during motor operation. This contributes to smoother motion, especially in dynamic systems.
Q: What is the function of shielding in the 457 mm power and feedback cables?
A: The shielding protects signal integrity and reduces electromagnetic interference. This ensures accurate feedback and consistent power delivery in noisy industrial environments.
