Compressor drives can be more dynamic than a steady-running power figure suggests. Loaded starts, cycling and torque pulsation can change what the coupling sees even when the motor nameplate looks ordinary.<\/p>\n
First identify models that cover nominal torque, speed and both bores. Then describe how the compressor starts and runs. The NM table does not provide a universal overload multiplier, so do not apply an unconfirmed overload factor. Send the start, cycling and shock conditions for application review.<\/p>\n
Base conditions and attached equipment can move the shafts after initial assembly. Use the model-specific radial and angular values as boundaries and investigate repeated elastomer damage instead of treating it as normal consumable wear.<\/p>\n
