Explosion Proof Motors – XP100

General Description

The SIMOTICS XP100 Explosion Proof motor is the workhorse of hazardous environments all over North America. Industries from grain handling and processing, oil and gas, and mining to pulp and paper, water and wastewater, chemical processing and more depend on this motor for safety, efficiency and long-life performance.

These motors are designed and manufactured to meet or exceed NEMA Premium® efficiency (MG1 Table 12-12) as well as the high requirements for safety and protection established by NFPA 70: National Electrical Code® (NEC). They are UL listed for different hazardous atmospheres for gas and dust protection. Their IP65 ingress protection keeps all dust out of the motors, providing reliability and safety assurance. All XP100 motors are UL certified and nameplated for VFD use. IEC Ex certification is available as an option.

Frame and End Shields

The SIMOTICS XP100 and XP100 ID1 Explosion Proof motors feature cast iron frames, end shields and an easy to access diagonally-split, oversized terminal box. The terminal box is provided with a neoprene gasket and includes a heavy duty ground lug and non-wicking leads that are clearly and permanently marked.  These characteristics plus high strength zinc-plated hardware, epoxy paint and stainless steel nameplates provide exceptional structural integrity and resistance to rust and corrosion, making them suitable for severe duty applications in harsh environments.

Rotor and Stator Windings

A unique offset rotor bar design provides improved efficiency. Larger bars and end rings reduce resistance for lower rotor losses. Each die cast aluminum rotor assembly is dynamically balanced for extended bearing life and includes a high-strength carbon steel (C1045) shaft for maximum performance. 

The stator is manufactured with premium electrical C5-grade steel laminations and copper electrical magnet wire that furthers the reduction in losses.

Insulation

The proprietary Class F non-hygroscopic insulation system with NEMA Class B temperature rise provides an extra margin of thermal life. The varnish system ensures maximum wire penetration to provide protection from moisture, corrosion and electrical shock. This insulation system meets or exceeds NEMA MG1 2014 Part 31 making the motors suitable for variable speed drives in constant torque (4:1) and variable torque (20:1). All windings are tested for CIV.

Cooling System

A non-sparking, bi-directional fan is locked and keyed to the shaft. Its low-inertia design reduces windage losses, improves airflow, reduces noise and provides dependable cooling. Cast Iron fan covers are standard for all frames sizes.

Bearings

Single shielded bearings are used for better bearing protection against contaminants.
