Product Description

The Kollmorgen U9D-A/TERMINAL is a ServoDisc series motor. The peak torque of the motor is 319.9 N-cm. The rated speed of the motor is 3000 RPM. The rated continuous torque of the U9D-A/TERMINAL at 25 degrees Celsius is 35.3 N-cm. The rated continuous torque of the motor at 40 degrees Celsius is 32 N-cm. The power output of the motor is 109 Watts. The maximum recommended speed of the U9D-A/TERMINAL motor is 6000 RPM. The continuous stall torque is 27.5 N-cm and the cogging torque is 0 N-cm. The electrical specifications for the motor include 23 Volts rated terminal voltage, 8.67 Amps rated continuous current, 72 Amps peak current and 6.8 Amps continuous stall current. Specifications for the motor winding include 0.85 Ohms terminal resistance, 0.66 Ohms armature resistance, 5 Volts/kRPM back EMP, 4.8 N-cm/Amp torque constant and armature resistance of less than 0.03 millihenry.

The mechanical time constant of the U9D-A/TERMINAL motor is 11.27 milliseconds. The electrical time constant is less than 0.05 milliseconds. The continuous power rate for the motor is 3.07 kilowatts per seconds. Thermal resistance at rated speed is 1.3 ºC/Watt. The thermal resistance at stall is 2.4 ºC/Watt. Options for ServoDisc motors include integral tachometers, external tachometers, optical encoders, fail-safe brakes, aluminum armatures, hardened commutators, forced air cooling, dust cover with CPC, industrial cover with MS connector, IP65 water resistance and different cable and connector options. The U9D-A/TERMINAL is a Platinum series motor. The Platinum series is a direct replacement for U-series motors. The Platinum motors feature zero cogging for smooth operation at low speeds and allow for easy field replaceable brush assembly. Trained personnel should install and operate the U9D-A/TERMINAL motor.
