SKU CH-7Q2N-6FS1A

A 12 V DC permanent-magnet motor delivering 1/4 HP at 800 RPM with 8.8 in-lb torque in a 56C frame

  • ColorTransparent
  • 1/4 HP permanent-magnet torque for HVAC actuators
  • 12 V DC supply matches vehicle and industrial buses
  • 800 RPM nameplate speed suits fan and damper drives
  • 56C face-mount with removable base fits standard brackets
  • Totally enclosed non-ventilated housing resists dust and moisture

Motor Specifications

The Leeson 108045.00 is a 12V DC permanent magnet motor rated at 1/4 HP and 800 RPM. It delivers 8.8 in-lb of full-load torque while drawing 21.0 A. The 56C frame suits HVAC control applications requiring precise speed regulation.

Build Integration

A 56C face and base mounting pattern with a removable base fits standard gearboxes or driven equipment. The 5/8 inch shaft diameter and 1 7/8 inch shaft length accept common couplings or pulleys. CW and CCW rotation is selectable for installation flexibility.

Thermals and Power

Class F insulation supports a maximum ambient temperature of 40 degrees C. The totally enclosed non-ventilated enclosure protects internal components without external airflow. No thermal protection is fitted, so the 21.0 A full-load current must be managed by the supply circuit.

Questions about this item

How long can the 1/4 HP motor run continuously at 8.8 in-lb torque before the 40 °C ambient limit becomes a concern?

The motor is rated for a maximum ambient temperature of 40 °C with no built-in thermal protection, so sustained operation near full load in warm environments requires external cooling or duty-cycle management.

What is the typical audible and thermal profile when the 12 V DC motor draws 21.0 A all day?

At full-load current of 21.0 A the brush-type carbon commutator and totally enclosed non-ventilated housing will generate noticeable heat and a steady brush hum; expect surface temperatures to rise well above ambient.

Which mounting hardware and shaft coupling are needed to install the 56C face/base frame with a 5/8 in shaft?

The motor uses a standard 56C face mount with a removable base and a 5/8 in diameter shaft 1 7/8 in long, so you will need matching 56C flange bolts, a 5/8 in bore coupling or pulley, and a key for the keyway.
