Mechanical Time Constant of Motor in Electric Traction Formulas

Mechanical Time Constant of Motor is defined as the time taken by motor to reach its synchronous speed from standstill under constant accelerating torque equal to the maximum torque of the motor. And is denoted by τ_m. Mechanical Time Constant of Motor is usually measured using the Second for Time. Note that the value of Mechanical Time Constant of Motor is always positive.
