Product Description:
Part of Kollmorgen's Goldline B and BH motor family, the B-204-B-21-S is developed for demanding industrial automation applications. This motor runs at 230V with 127Hz but can also be specified for 400V. At 230V, it delivers 2.44 Nm continuous torque at 3800 RPM. 2.44 Nm is the amount of torque the motor can provide for continuous operation. 3800 RPM is the speed of the output shaft under the specified load conditions. The motor's stationary torque is 66 Nm. This is the amount of torque the motor can provide when it’s not rotating, a critical aspect for applications that require high initial force to overcome static friction or load inertia. At 400V, the Kollmorgen B-204-B-21-S has a rated speed of 3000 min⁻¹. This is the motor's speed when the voltage is increased. This illustrates how voltage affects the motor's capacity to generate force.
The rated torque at 400V is 75.7 Nm, which is much more than the torque at 230V. At 400V, the rated power is 12.4 kW, and the rated current is 20.3 A. The torque per unit of current, or torque constant, is 1.92 Nm/A. This is crucial to comprehending the torque-producing efficiency of the motor. The motor's electromotive force, or back-EMF, is 107 mV/min⁻¹, which is its voltage constant. For regulating the motor's speed in a variety of applications, this is crucial. These constants provide us with essential details regarding the electrical properties of the motor and how it behaves in various operating scenarios.
The motor draws the stationary current, which is 39.7 A when it is maintained at its rated voltage. This is crucial for figuring out the power supply's dimensions and the motor's starting characteristics. The peak current of the B-204-B-21-S is 66.8 A, which is another electrical feature. For applications involving dynamic loads or abrupt acceleration, this is the maximum current the motor can handle for a brief period of time. Phase-to-phase winding resistance is 0.53 Ω. This resistance impacts the motor's efficiency and heat production. Reduced heat and increased efficiency are the results of lower winding resistance. This is crucial for the longevity and dependability of the motor, mainly when it is operating continuously.
