Product Description:
The PMA43P-00100-00 is a servo motor from Pacific Scientific that is designed in a 142 mm square frame size. It features IP65 protection rating for dust/moisture resistance and it possess insulation of category H for high-temperature endurance. This motor has a thermal dissipation value of 30 minutes and it comes in a rugged TENV housing.
The PMA43P-00100-00 motor generates a continuous stall torque of 6.1 Nm and its rated speed is 1850 RPM at 240V AC while its peak operating speed can go up to 6800 RPM. It provides a typical torque of 4.9 Nm at 480 VAC and its peak torque measures 21.7 Nm. This motor uses a combination of neodymium-iron-boron magnets for high energy density and its internal structure is compose of 6 pole pairs. It is equipped with a smooth shaft in accordance with DIN 42995N standard that measures 1.9 cm in thickness and 4.0 cm in length. There is no brake included in this model and it relies on resolver feedback system for precise motor positioning and speed control. Its torque constant is 1.34 Nm/A and its current required at peak torque is 18.4 A. This PMA43P motor utilizes a stationary current of 4.6 A and its winding resistance is measured as 3.9 Ohms, between lines. Its inductance has a minimum value of 13 mH and possess a thermal resistance rated at 0.59 °C/Watt.
The PMA43P-00100-00 motor is presented with top mounted 6 pin power and 12 pin sensor connector for wiring. Its static friction is specified as 0.15 Nm for startup stability and its viscous damping factor is specified as 0.05 Nm/kRPM. The PMA43P motor’s rotational inertia is 0.0046 kg·m² and it carries a mass of 7.6 kg.
Frequently Asked Questions about PMA43P-00100-00:
Q: Why does the PMA43P-00100-00 motor use neodymium-iron-boron magnets?
