AC induction motors serve as the continuous workhorse for modern industrial equipment, commercial HVAC systems, fluid movement, and automated machinery. However, off-the-shelf catalog motors are designed for median operating requirements—forcing design engineers to make compromises on mounting footprints, thermal dissipation, speed-torque profiles, and energy efficiency.
Since 1985, Telco Intercontinental Corp. has bridged the gap between standard electric motor platforms and full custom OEM requirements. We engineer AC motors tailored precisely to your voltage source (115V to 480V AC), pole configuration, insulation class, and environmental enclosure rating. Whether your program demands a quiet Permanent Split Capacitor (PSC) motor for medical ventilation or a rugged 3-phase TEFC induction motor for industrial pumping, our US-based engineering team guides your product from initial specification review to volume release.
Every Telco AC motor program is structured to lower long-term operating costs, streamline assembly, and ensure continuous operation in critical applications.
AC induction motors eliminate mechanical brushes and commutators, drastically minimizing maintenance downtime and wear points across decades of operation.
Custom winding patterns and optimized lamination stacks ensure compliance with global energy regulations, delivering lower lifecycle electrical consumption.
Designed for sustained duty under rated loads without thermal degradation. Optional Class H insulation and sealed enclosures accommodate severe environments.
Use this parameter reference as an initial technical guide. Telco customizes electrical windings, stack lengths, shafting, and electrical interfaces to match your exact mechanical design.
