Tips: Simple CalculationPrinciple for Select Brake Motor.

The choice of brake model depends to a large extent on the required braking torque. In addition, factors such as braking moment of inertia, relative speed, braking time, and operating frequency should also be considered. The following are the styling rules recommended by a certain brake manufacturer. Different manufacturers will have some differences, but the principles are similar.
Calculate the required braking torque: T=K×9550×P/n
Among them:
T——Required braking torque (N.m)
P——Transmission power (kW)
n——Relative speed when the brake is applied (r/min)
K safety factor (take K>2)
