Rated temperature rise: refers to the ambient temperature specified in the design(40℃)Under, the maximum allowable temperature rise of the winding of an asynchronous motor, which depends on the insulation grade of the winding. (unit)K)
Allowable temperature rise: refers to the temperature of the motor compared to the ambient temperature limit
efficiencyηThe ratio of the mechanical output power of the motor to the electrical input power, usually expressed as a percentage
Rated efficiency (ηN) : refers to the efficiency of rated operation
Rated power factor (cosφN) :Three-phase asynchronous motorPower factor at rated operating time
Phase number: The number of coil groups, two, three, four, five phase stepper motor respectively2,3,4,5Coil assembly
Stator winding: refers to the winding installed on the stator,The copper wire that goes around the stator. Winding is a general term for a phase or an entire electromagnetic circuit composed of multiple coils or groups of coils
Rotor winding: The group of coils wound and connected according to a certain law in the armature of the motor is called the rotor winding. It is one of the main components to realize the electromechanical energy conversion in the motor
Armature winding: composed of a certain number of armature coils connected according to a certain law, it is the circuit part of the DC motor, and it is also the part of the induced electromotive force and electromagnetic torque for electromechanical energy conversion
Noise: When the motor is running in no-load steady stateAWeight sound power leveldB(A) maximum value
Vibrations:Three-phase asynchronous motorEffective value of vibration velocity under no-load steady operation (mm/s)
