Product Description:
The model U12M4 is a high performance DC motor manufactured by Kollmorgen. It is designed for demanding industrial applications requiring robust torque, high efficiency and reliability. The motor features a peak torque of 1316 oz-in and a rated speed of 3000 RPM to deliver a continuous power output of 284 watts.
This ServoDisc series DC motor operates at a rated terminal voltage of 43.4 volts and can handle a continuous current of 8.8 amps under normal load conditions. It is capable of reaching a peak current of 85 amps during short bursts of high power demand. The motor delivers a rated continuous torque of 128 oz-in and a continuous stall torque of 122 oz-in for both standard and heavy duty tasks. It is designed to perform at high rotational speeds while maintaining operational efficiency with a maximum recommended speed of 6000 RPM. The motor features a static friction torque of 5.5 oz-in which aids in smoother startup and reduced wear during initial operation. The motor offers a good balance between performance and durability with a total weight of 8 lbs. It also benefits from a low continuous stall current of 8.1 amps which ensures reliable performance even under heavy loads.
The U12M4 DC motor has a terminal resistance of 0.750 ohms (± 10 %) and an armature resistance of 0.610 ohms (± 10 %). The armature inductance is less than 100 µH which helps minimize electrical losses and enhances motor response. The viscous damping constant is 1.8 oz-in/KRPM that contributes to smoother operation by reducing oscillations. The motor's moment of inertia is 0.0190 oz-in-sec² which ensures quick acceleration and deceleration for precise control in dynamic applications.
