SKU CH-X2BG-Z2ED3

Three-phase TEFC motor delivers 1/3 HP at 1140 RPM with 230/460 V AC input and 70% nominal efficiency

  • Product typeMotors
  • Three-phase power delivers smooth industrial torque
  • TEFC enclosure protects windings from dust and moisture
  • 1/3 HP at 1140 RPM suits constant-speed drives
  • Rigid 56-frame steel base ensures solid foot mounting
  • Class B insulation with 1.35 service factor handles 40 °C ambient

Industrial three-phase motor

The Baldor-Reliance M3535 is a general-purpose 21/64 HP three-phase motor built for continuous-duty operation in industrial environments. Its TEFC enclosure and steel frame suit equipment builders and maintenance teams needing reliable power for conveyors, pumps or fans.

Thermal and electrical profile

Totally enclosed fan-cooled construction handles a maximum ambient temperature of 40 degrees C while insulation class B and a 1.35 service factor manage heat during extended runs. The motor draws 1.8 amps at 230V or 0.9 amps at 460V, delivering 1140 RPM at 60 Hz with a nominal efficiency of 70 percent.

Mounting and protection details

A rigid 56-frame base provides secure foot mounting for fixed installations. Ball bearings support the shaft for bidirectional CW/CCW rotation, though the unit ships without built-in thermal protection. CSA and UR markings confirm compliance for North American industrial use.

Questions about this item

How do I wire the 230/460 V three-phase supply to the nine-lead terminal block on this frame 56 motor?

Connect the nine leads in the low-voltage (230 V) or high-voltage (460 V) pattern shown on the nameplate diagram; the most common mistake is leaving a pair unlinked, which creates single-phasing and overheating.

Which parts will need replacement after extended operation at 1140 RPM?

The ball bearings are the primary wear item; inspect them at regular intervals and replace when vibration or noise increases, since no other user-serviceable components are specified.

What thermal limit appears first when the motor runs continuously at 1.35 service factor in a 40 °C ambient?

The Class B insulation reaches its temperature rise ceiling before the 70 % nominal efficiency drops, so sustained overloads above nameplate current will trip the thermal limit first.
