Design Electromagnetic Device

Design a practical electromagnetic device by specifying performance requirements, selecting an appropriate topology, calculating design parameters from electromagnetic first principles, analyzing losses and efficiency, and validating the design against physical constraints including thermal limits and material saturation.

When to Use

• Sizing an electromagnet (solenoid or toroidal) for a target field strength, pull force, or holding force
• Selecting motor topology (DC brushed, brushless DC, stepper, induction) and computing torque, speed, and efficiency
• Designing a generator for a specified voltage, current, and frequency output
• Designing a transformer for a given voltage ratio, power rating, and frequency
• Analyzing and minimizing losses: copper (I^2 R), core (hysteresis and eddy current), stray flux

Inputs

• Required: Device type (electromagnet, motor, generator, or transformer)
• Required: Performance requirements (field strength, force, torque, voltage ratio, power, efficiency target)
• Required: Operating conditions (supply voltage and current, frequency, duty cycle, ambient temperature)
• Optional: Preferred core material (silicon steel, ferrite, powdered iron, air core) with B-H data
• Optional: Size and weight constraints
