What to do when your current motor is end-of-life

Due to the constant update in both winding and magnet technologies, motors can go into NRND (Not Recommended for New Designs) status and eventually become obsolete. It is a standard process to replace older motors with more modern options, perhaps for a more compact design or for competing lead times or pricing.

Technology updates result in improved efficiency, torque and speed output; whilst this is highly beneficial for placing newer and smaller motors in tighter applications, it can cause problems for integration into legacy designs A range of parameters should be considered when replacing DC or BLDC motors.

To guide you through the process, the experts at Maxon have produced a finding alternative motors focusing on these key parameters, including motor behaviour, power limitations, motor type, electrical interfaces, mechanical interfaces, combinations, commercial aspects, operation, duty cycle and motion profile.
