Product Description

The M-105-A-21 is a medium inertia servo motor from Kollmorgen. It has a 10-inch frame, 5 stacks, and a speed rating of 5600 revolutions per minute. Its operating voltage is rated at 230 Volts. The M-105-A-21 is part of Kollmorgen brushless motors. This type of motors can be used in a variety of industrial environments since its brushless nature lowers its maintenance needs. Additionally, its brushless nature lowers electromagnetic interference. With a waterproof (IP65) rating plus minimal maintenance, the M-105-A-21 has a longer service life. The M-105-A-21 falls in the Kollmorgen M series motors.

Motors in this family feature a rugged resolver feedback, rear shaft extension, a large torque to volume ratio, and in-built thermostat. The M-105-A-21 belongs to the Class H insulation. Motors in this simulation class have maximum permissible winding temperature of 180 degrees Celsius. Options supported by the motor include mating connectors, NEMA connectors, front mounted gearheads, and IP 67 sealing. Note that an IP 67 rating protect the motor even when submerged in water while IP 65 protects the motor against water coming from a nozzle. The motor employs the highest energy rare earth neodymium-iron-boron magnets which helps the motor in delivering exceptional continuous torque and peak torque performance.

The M-105-A-21, as with other Kollmorgen Goldline series motors, supports a wide range of industrial applications due to its optimum performance and value. Note that motors in the Goldline series support control using the Kollmorgen ServoStar digital amplifier. Combining the amplifier and the motor produces a high performance motion control system. The motor weighs 3.2 kilograms, a horsepower rating or 0.73 HP, a static friction rating of 0.04 N-m, and a thermal resistance at stall of 1.30 degrees Celsius per Watt.
