U12M4HA

Product Description:

U12M4HA is a servo motor. It belongs to the ServoDisc U-series from Kollmorgen. An amplifier from the EM19 or KXA Plus series must be used with the motor. The amplifier performs two functions: it supplies power for the motor and controls motor speed and output torque. The motor has a flat disc armature which allows design of compact motors. With the low profile, the motor is suited to applications that require high torsional stiffness, precise speed control, and long brush life in a compact package. The magnets on the motor are mounted on the end plates, and create an axial magnetic field that runs parallel to the main shaft. There is a very small gap between the magnets and the motor creates torque when the current flows through the copper conductors interacts with the magnetic field created by the magnets.

Peak torque output of the U12M4HA motor is 1130 N-cm. Rated speed of the servo motor is 3000 RPM and the recommended maximum speed is 6000 RPM. Power output of the U12M4HA motor is 329 Watts. Continuous torque rating of the motor at 25 degrees Celsius is 104 N-cm. Continuous torque rating of the motor at 40 degrees Celsius is 94 N-cm. The continuous stall rating is 106 N-cm. Electrical specifications for the motor include 65.6 Volts terminal voltage, 6.5 Amps continuous current, 65 Amps peak current and 6.3 Amps continuous stall current. Inductance of the motor winding armature is less than 100 microhenry. Resistance of the armature is 1.030 Ohms and the terminal resistance is 1.17 Ohms. Mechanical specifications for the motor include 5 kilograms weight, 5.5 inches diameter and 2.78 inches length.
