Product Description:
The KBM-79H03-E03 is a direct drive rotary motor assembly from Kollmorgen, a leading motion control solutions provider. This motor is part of the KBM series designed for industrial automation. The direct drive design means the load is coupled directly to the motor shaft; no gears or belts are required. This eliminates backlash, which is critical in applications where high precision is required, such as robotics and CNC machining. The absence of intermediate components also means increased efficiency and less maintenance. This Kollmorgen motor is 24V and 200W. This is a measure of the motor’s ability to do work and affects its torque and speed capabilities. The rated torque is 2 Nm, which is the rotational force the motor can produce.
Torque is what accelerates and maintains the rotation of the load. The motor’s rated speed is 1000 RPM, which is the number of shaft revolutions per minute. The combination of torque and speed determines the motor’s power output. At rated power, the speed is 290 RPM. The torque sensitivity is 11.0 Nm/Arms, which is the torque per unit of current applied. Other performance characteristics include a back EMF constant of 664 Vrms/kRPM. Back EMF is the voltage generated by the motor as it rotates proportional to its speed. This is important for controlling the motor’s speed and determining its operating characteristics. The motor constant is 7.29 Nm/√watt, which relates the motor’s torque output to the square root of the power input. This is useful for comparing the efficiency of different motors. The line-to-line resistance of the motor windings is 1.47 Ohms, and the inductance is 8.9 mH.
These electrical parameters are important to understand the motor’s electrical behavior and how it responds to control signals and its efficiency. The resistance affects the current draw for a given voltage and the inductance affects the rate of change of current. The physical characteristics of the KBM-79H03-E03 are also important. The KBM version of the motor weighs 32.1 kg and has an inertia of 0.114 Kgm², and the KBMS version weighs 33.5 kg and has an inertia of 0.125 Kgm². Inertia is the motor’s resistance to change in rotation speed. A higher inertia requires more torque to accelerate or decelerate the motor. The weight of the motor is important to consider when integrating the motor into the overall system design especially where weight is a constraint.
