Product Description:
JR33M6CH is a motor from Kollmorgen with low space requirements and very fast acceleration rates. Its nominal speed is <<3000 RPM, which can go up to a recommended maximum value of 5000 RPM. The peak accelerate rate of the motor is 19.4 kRad/s2. Mechanical time constant of the motor is 5.83 ms and the electrical time constant is less than 0.56 ms. Continuous power output rate that the motor can deliver is 48.5 kW/s. Thermal resistance of the motor at rated speed is 0.11 degrees Celsius per Watt. The thermal resistance at stall is 0.40 degrees Celsius per Watt. The forced air thermal resistance is 0.23 degrees Celsius per Watt with 2 lbs/min forced air. The peak output torque is 451.9 N-cm, the continuous stall torque is 28.7 N-cm, and the continuous torque is 33.6 N-cm at 25 degrees and 30 N-cm at 40 degrees Celsius.
Power output of the JR33M6CH motor is 10550 Watts or 14.14 Horsepower. The motor has zero cogging torque, which leads to smoother and more efficient motor operation. Cogging torque refers to the uneven torque produced by a motor due to the interaction between the permanent magnets and the stator slots in the motor. The absence of cogging torque minimizes mechanical vibrations, resulting in quieter operation. Motors with zero cogging torque perform more effectively at low speeds. The rated voltage at the motor terminals is 246 Volts. Peak current output of the motor unit is 600 Amps. Kollmorgen has designed the motor with a flat disc armature, which gives the motor a low profile. This is advantageous for applications that have limited available space. Rugged housing of the motor provides robust ingress protection.
