Q5: What are the motor’s rated power and torque?
The rated output power is approximately 0.27 kW, and the continuous stall torque is 0.49 N·m. The peak stall torque is approximately 1.58 N·m.
Q6: What are the dimensions and weight of this motor?
The motor has a 63 mm frame and a 50.8 mm magnet stack. Its approximate weight is 1.64 kg. Exact external dimensions should be checked against the mechanical drawing before installation.
Q7: Which servo drives are compatible with the MPL-B1520U-VJ44AA?
Compatibility depends on the drive’s voltage class, motor feedback interface, brake wiring, and connector arrangement. Confirm the complete motor catalog number against the servo drive’s supported motor list before connecting it.
Q8: What should be checked when replacing this motor?
Verify the full model number, voltage rating, shaft and flange dimensions, encoder type, brake voltage, connector configuration, and mounting requirements. Because this model is listed as discontinued by some suppliers, inspect the nameplate and confirm the condition and specifications of any replacement unit before installation.
