The MPJ’s inertia boost comes from its special inertia flywheel, which adds from three to 10 times the inertia of a standard MPP servo motor. This flywheel replaces the more expensive gearbox the vendor traditionally added to the motor for applications where the customer has a high load-to-rotor inertia mismatch. Now, on these applications, users can simply use an MPJ motor, saving money and eliminating the speed constraints normally associated with a gearhead. MPJ motors are available in sizes 92, 100, 115 and 142, with continuous torque ranging from 1.3Nm (12lb-in) to 20Nm (173lb-in).
