Variable Speed Induction Motor - Panasonic M41A1G4L Operating Instructions Manual

Motor selection
Inertia
Life of motor brake
Load inertia affects a lot to the life of the brake.
In the case of brake unit and variable speed motor, braking life is 2 million cycles, and in the case of a motor with
electromagnetic brake, life is one million cycles.
Motor self-inertia, average acceleration torque and permissible load inertia
• When using single-phase induction motor and brake unit
• When using single-phase variable speed induction motor and electric brake of speed controller
• When using 3-phase induction motor and brake unit
