This is particularly true for the aerospace and automotive sectors where size, weight and efficiency are driving the design of machines. [6] [7] [8] The design approach often taken is to consider both electromagnetic and thermal aspects of a machines design at the early stages in machine design, [9] [10] where Motor-CAD allows this to be done.
An axial flux motor (axial gap motor, or pancake motor) is a geometry of electric motor construction where the gap between the rotor and stator, and therefore the direction of magnetic flux between the two, is aligned parallel with the axis of rotation, rather than radially as with the concentric cylindrical geometry of the more common radial ...
However it complicates the electrical design, because a switching system must deliver power to the different windings and limit torque ripple. [1] [2] Sources disagree on whether it is a type of stepper motor. [3] The simplest SRM has the lowest construction cost of any electric motor. Industrial motors may have some cost reduction due to the ...
An industrial electric motor . An electric motor is a machine that converts electrical energy into mechanical energy.Most electric motors operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor's shaft.
Now, if this motor is fed with current of 2 A and assuming that back-EMF is exactly 2 V, it is rotating at 7200 rpm and the mechanical power is 4 W, and the force on rotor is = N or 0.0053 N. The torque on shaft is 0.0053 N⋅m at 2 A because of the assumed radius of the rotor (exactly 1 m).
The rotating shaft of the motor was also the axle for the wheels. In the case of French TGV power cars, a motor mounted to the power car's frame drives each axle; a "tripod" drive allows a small amount of flexibility in the drive train allowing the trucks bogies to pivot. By mounting the relatively heavy traction motor directly to the power car ...
