Product Description:

The PWM3624-5437-7-1 motor is manufactured by Pacific Scientific and is supplied within the PWM Brushed Treadmill Motors series. This permanent-magnet DC unit converts filtered pulse-width-modulated drive signals into mechanical rotation for material-handling and fitness conveyors that require consistent belt speed. In automated stations, it serves as a compact prime mover where variable speed and moderate torque are needed for steady belt-driven motion.

This model operates from a supply of 120 VDC and delivers up to 2 HP of mechanical output at a base speed of 3600 RPM. Because it is a permanent-magnet DC motor, torque is produced by fixed magnets instead of field windings, which simplifies the power stage and improves efficiency at partial load. The drive expects a filtered PWM signal, and the built-in inductance together with an external filter smooths duty-cycle transitions so armature current remains within commutation limits. Pacific Scientific uses an anti-cog magnet layout that reduces detent torque and helps keep belt motion even at low speed. The armature windings are polyester impregnated to protect the copper from abrasion and moisture, while a fused commutator helps limit flash-over during high current spikes and constant-force brush springs maintain uniform contact pressure.

The rotor runs on large sealed bearings that retain lubrication and help block airborne contaminants common in gyms or industrial floor environments. The motor uses field-replaceable brushes, so brush service can be completed without disassembling the end bell or disturbing alignment. Electrical terminations pass through a gasketed conduit box that helps shield the lead connections from sweat, oil, or washdown spray. These service-oriented features support stable commutation and steady operation during continuous-duty use under filtered PWM control.
