Product Description:

The BA3628-7012-9-48BP is a permanent-magnet direct-current motor manufactured by Pacific Scientific as part of its Permanent Magnet DC Motors series. Designed for material-handling, mobile platforms, and compact machinery, the unit converts low-voltage electrical energy into shaft rotation without relying on field windings. Its magnet topology and sealed frame make it suitable for integration into automation zones where space is limited and minimal maintenance downtime is required.

The motor accepts a low-voltage DC input, allowing operation from battery packs or switch-mode supplies typically used on autonomous or transport equipment. A PWM/battery-rated control interface keeps speed stable under variable loads by modulating average armature voltage. Rated output velocity reaches 1750 RPM, a speed point that aligns with common gearbox ratios for conveyors and pumps. Internal anti-cogging magnets smooth the torque profile so feedback devices see fewer velocity ripples at low speeds. The housing is a TENV enclosure, meaning totally enclosed, nonventilated construction that protects internal components while relying on surface radiation for heat removal. Long-life operation is further supported by large sealed bearings that keep lubricant contained and airborne contaminants out, reducing periodic service needs.

Maintenance features complement the electrical and mechanical design. The armature’s brushes are field-replaceable, so worn parts can be replaced without removing the motor from the machine base. These brushes are held in place by constant force brush springs, ensuring contact pressure remains stable as the carbon shortens, which minimizes arcing and commutator wear. As a PMDC machine, torque production stays linear with current, simplifying current-loop tuning when the motor is tied to digital drives or battery management systems.
