Electric Motor Model
Product Code : SCL-PLE-11670
The StemAids Electric Motor Model is a dual-purpose electromechanical demonstrator engineered for the empirical study of the Motor Principle and additive color theory. Optimized for Secondary and Vocational STEM curricula, this apparatus facilitates the quantification of Lorentz force (F=BIL) and the visualization of white light synthesis via high-velocity rotation. Manufactured to ISO 9001:2015 standards, it provides a ruggedized platform for verifying the conversion of electrical energy into mechanical work within institutional laboratory environments.

Key Pedagogical Outcomes (Bloom’s Taxonomy Alignment)
- open-frame armature architecture: facilitates student visualization of magnetic flux interaction and coil rotation, supporting Electromagnetism Module 201.
- split-ring commutator interface: enables the physical study of current reversal, allowing learners to apply torque consistency principles to rotational motion.
- integrated newton’s disc: supports the analysis of additive color mixing, where high-speed rotation causes the brain to fuse spectral colors into a neutral white/grey.
- electromechanical efficiency evaluation: allows students to evaluate the relationship between input voltage, rotational velocity, and the resulting chromatic fusion quality.
International Logistics & Compliance
StemAids ensures comprehensive OEM readiness for global institutional procurement:
- packaging: export-grade seaworthy crating (ISPM-15 compliant) with specialized internal stabilization to protect the delicate commutator alignment and rotor balance.
- documentation: includes Manufacturer’s Authorization Form (MAF), Certificate of Conformance (CoC), and illustrated Technical User Manuals in English.
- durability: tropicalized design featuring corrosion-resistant commutator surfaces and UV-stable color disc pigments for reliable performance in varied climates.
Direct OEM Sourcing Advantages
Procuring the StemAids Electric Motor Model directly ensures vertical manufacturing control:
- in-house precision balancing: rotors are batch-tested for minimal vibration to ensure high-velocity stability during color disc demonstrations.
- batch-tested for uniform reliability: every unit undergoes a startup voltage verification to ensure low-friction commutation across all production lots.
- direct factory spares availability: guaranteed availability of replacement brushes, color discs, and armature assemblies to maximize long-term laboratory ROI.
- manufacturing control: direct oversight of magnetic flux density and winding resistance ensures consistent performance standards for large-scale institutional rollouts.
