electrical time constant (ms)

Definition

The appropriate product category Servomotors / Servo Drivers: The transient response time to the current that flows to the armature of a motor to which a power supply voltage is applied. It is expressed by this formula: Electrical time constant = Armature inductance/Armature resistance. Because a smaller value enables the current wave to rise more quickly, the transient response time to the current is faster.
