1.Step angle-Step angle is the angle of rotation that occurs when the motor receives one pulse power. It also determines the resolution of the motors movement. The accuracy of the stepper motors movement is also determined by the step angle.
2.Holding torque- Holding torque is the amount of torque that the motor can produce at a standstill. Usually not affected by speed, the torque output drops slightly when the motor accelerates.
3.Resistance-This is the amount of resistance in the coils of the stepper motor and can be used to measure the winding of the motor.
4.Inductance-The Inductance of a stepper motor is a measure of how much current is required to generate a given amount of torque.
5.RMS Current-RMS (Root Mean Square) Current is the amount of current that a stepper motor can safely draw without heating up the motor too much.
6.Detent torque-Detent torque is the motors resistance to rotating when no power is applied. It helps to prevent the motor from moving under uncontrolled conditions.
7.Pole pairs-The number of pole pairs determines how many steps the motor will make in one revolution.
8.Pulse-Pulse is a signal used to control a stepper motor. It determines the angle the motor will rotate for each pulse it receives.
9.Stator length-Stator length is the distance between the motors outer coils and is an indication of the motors physical size.
10.Lead-Lead is the length of copper wire that is wrapped around each winding of the motor and determines the voltage required to drive the motor.
11.Bearing type-Bearing type refers to the type of bearing used in the construction of the stepper motor. Different types of bearing can result in different levels of torque.
12.Max speed-Maxspeed is the top speed the motor can safely achieve without causing it to overheat.
13.Steps per revolution-Steps per revolution are the number of steps the stepper motor will make when it completes one full revolution.
14.Moment of inertia-Moment of inertia is the measure of resistance to acceleration when the motor is stationary. It is affected by the mass and size of the rotor.
15.Ambient temperature-Ambient temperature is the temperature of the environment in which the stepper motor is located and can influence its performance.
