Industrial Variable Speed A-C Motors
The Reliance is an integrated motor and control product offering power matched variable speed performance in a single package.
Applications Material Handling. Fluid Handling. Air Handling/HVAC. Mixing.
Position Simple, cost-effective alternative to A-C or D-C drive/motor combinations as well as belt/pulley and traction type mechanical adjustable-speed drives. Easy-to-Use Lowers Installation Costs Reliable Operation Flexible and Compact
Easy to Use Variable speed motor without the complexity of a full function drive. Intuitive operation eliminates operator training while maximizing productivity by reducing the chance of operator error. Remembers previously set speed for production consistency. LED fault indication speeds troubleshooting (overcurrent, over temperature, etc.).
Lowers Installation Costs Eliminates the need for a push-button start/stop switch (mechanical drive replacement). Single preconfigured unit to mount and wire instead of two. Only requires connecting two power leads. All other leads are preconnected. Optimal plug-in remote operator control minimizes on-site wiring costs.
Meets U.L. and CSA standards. Power matched motor and controller. Reliable Operation Volts per Hz ratio is specifically matched. Immunity to insulation damaging voltage spikes ( dv/dt ). VSM package rated like a motor. Single-phase input, three-phase output. Designed and manufactured and built by Reliance Electric.
Foot or C-face mounting Bi-directional operation (via motor connection). 180 RPM through 2700 RPM speeds (4- pole motor). 4:1 constant torque or 10:1 variable torque operation. Enclosure is IP54 rated for use in harsh environments. Flexible & Compact
Flexible & Compact Integral operator control can be rotated in 90 o increments to meet various mounting requirements.
Flexible & Compact Optional remote operator control. Current limit rating of 150% accommodates hard to start loads or overloads. Compact size makes ideal for portable equipment.
