The A at the end of MDD021A distinguishes this motor-length and torque package from neighboring variants in the same MDD021 frame. A later letter generally indicates a longer active motor and greater torque capability, but the factory planning data and complete nameplate govern the exact performance.
Use the complete part number to verify the winding, feedback, brake, shaft, centering, cooling and connector configuration before ordering or substituting a motor.
