Item # 1302, Up to 0.25 Horsepower (hp) Small Permanent Magnet Direct Current (DC) Motor

IronHorse motors are manufactured by leading motor suppliers with over 20 and 45 years of experience delivering high-quality motors to the demanding U.S. market. Our suppliers test the motors during production and after final assembly. This is how we can stand behind our IronHorse motors with a two-year warranty (motors 1/3 HP and above); or one-year warranty (motors 1/4 HP and less).

IronHorse DC motors are designed for use on unfiltered SCR (Thyristor) type and PWM (pulse width modulated) type DC adjustable speed drives, and on across-the-line DC controls.

Additional Information
DC motors are designed for use on unfiltered SCR (Thyristor) type and PWM (pulse width modulated) type DC adjustable speed drives, and on across-the-line DC controls.

DC motors are designed for use with unfiltered SCR (Thyristor) type and PWM (pulse width modulated) type DC adjustable speed drives, and on across-the-line DC controls. DC motors are perfect for conveyors, turntables, anywhere adjustable speed and constant torque are required, or when dynamic braking and/or reversing are needed.


Features
  • Replacement brush sets
  • Simple two-lead connection
  • Class F insulation
  • 12VDC, 24VDC, 90VDC (can be used with 110VAC powered DC drives), and 180VDC (can be used with 230VAC powered DC drives)
  • Rated for SCR drives
  • Class F insulation
  • High energy ceramic magnets
  • Double shielded ball bearings
  • Dynamically balanced armature
  • Reversible design
  • 18-inch leads, or junction boxes with 8-inch leads
  • Externally replaceable brushes
  • Can be mounted in any orientation
  • Not intended for DC power generation


Applications
  • Conveyors
  • Turntables
  • Where adjustable speed and constant torque are required
  • When dynamic braking and reversing capabilities are needed


Form Factor
The voltage used to power a permanent magnet (PM) DC motor is not pure DC. It is derived by rectifying a supplied AC voltage. The resulting DC voltage has a ripple that is related to the frequency of the AC input.

Form factor is the ratio of Irms to Idc and indicates how close the driving voltage is to pure DC. The form factor for a DC battery is 1.0. The higher the form factor is above 1.0, the more it deviates from pure DC.

Form factor should not exceed 1.35 for continuous operation. Half wave rectification is not recommended as it drastically increases form factor.

Operating Ironhorse PMDC motors with DC voltages with form factors higher than 1.35 can result in premature brush failure and excessive motor heating.
