Company Profile:
The Motor & Motion Association is the manufacturing trade association for the electric motor and motion control industries. It promotes the electric motor industry through education, pre-competitive research and facilitation of technology transfer within the industry and in cooperation with ...
The time rate change of velocity. Torque (T) developed by the rotor (armature) ) will cause it to accelerate. α = T / J , Where J = polar moment of inertia.
Industry:Electrical equipment
An expression of maximum theoretical acceleration from stall (locked rotor) of an unloaded motor with maximum current (Im) applied, measured in rad/sec².
Industry:Electrical equipment
The temperature of the environment immediately surrounding the motor. It is measured in ºF or ºC.
Industry:Electrical equipment
The rotating portion of the magnetic structure that is found in machines with commutators.
Industry:Electrical equipment
A magnetic field is produced by the armature current. It is shifted approximately 90 electrical degrees with respect to the direction of the stator field. It causes the armature to rotate and tends to cause demagnetization of the trailing pole tips of the stator.
Industry:Electrical equipment
The shaft displacement along the motor axis which is due to a reversal of the axial force. It is measured in inches or mm.
Industry:Electrical equipment
The displacement measured when the moving force is removed after positioning the shaft axially from one extreme position to the other.
Industry:Electrical equipment
The displacement measured when a force of known value causes the shaft to move axially from one position to another. When specifying cushioned end play, the force and direction of movement must also be specified.
Industry:Electrical equipment
The value of torque that is required to begin motion of an armature or rotor that is de-energized and has been at rest.
Industry:Electrical equipment
The maximum torque developed by an induction motor at rated voltage and frequency without an abrupt drop in speed.
