About Rexroth MSK030C-0900-NN-M1-UG0-NNNN motors

Rexroth MSK servo motors are also advertised as IndraDyn S motors. This motor series boast power and precision, but requires a controlled environment.

MSK motors are not intended for underwater use. They work best at ambient temperatures lower than 100 ºF with a maximum humidity of 20% to 30%. They also need a dust-free environment and oil-free environment.

Here’s a breakdown of the MSK030C-0900-NN-M1-UG0-NNNN motor type code.

  • “MSK” tells you that the motor is an MSK, or IndraDyn S, motor. All Rexroth motor type codes begin with their motor family.
  • “030” indicates the size of the motor.
  • “C” is the length
  • “0900” is the winding
  • “NN” indicates the housing design. In this case, NN means natural convection.
  • “M1” is an optical encoder, multiturn-absolute Hiperface, with 128 increments.
  • “U” indicates that the motor has a rotatable 240º plug electrical connection.
  • “G” tells you that the motor has a smooth shaft with a shaft seal ring.
  • “0” means the motor does not have a holding brake.

Using an MSK030C-0900-NN-M1-UG0-NNNN motor in hot, humid, or dirty conditions can compromise the motor’s performance. MSK motors are self-cooling, but environmental factors can limit the motor’s ability to dissipate heat.
