Product Description:

The PMA23B-00114-00 is a brushless servo motor manufactured by Pacific Scientific within the PMA Brushless Motors series. This low-maintenance rotary actuator converts drive amplifier current into controlled shaft torque, allowing closed-loop positioning and speed regulation in pick-and-place modules, indexing tables, and other industrial automation axes where precise motion is required. Its brushless design helps reduce routine wear parts compared with brushed motors, which supports stable operation in equipment that runs through frequent start-stop cycles. High-resolution feedback comes from a digital encoder with commutation tracks that yields 2048 ppr, supplying the controller with precise angle data during every revolution and supporting accurate correction of load-related motion errors.

The motor can sustain a continuous stall torque of 2.0 Nm, providing enough steady-state force for holding or low-speed duties without overheating. Short bursts up to 7.2 Nm cover dynamic moves such as acceleration or rapid deceleration, so the axis can respond to changing motion demands without relying only on continuous torque capability. A winding nominal stall current of 2.7 ARMS sets the amplifier sizing point, while the winding voltage class of 240 V AC max indicates the upper supply level that may be applied. The laminated rotor contributes a reflected inertia of 0.055 kg·m² × 10⁻³, so drive tuning can achieve responsive yet stable control across most load couplings and common servo transmissions.

Mechanical integration is simplified by a square frame that measures 70 mm across the body, which helps the motor fit compact axis layouts where mounting space is limited. A right-angle, keyed power connector follows the 6PP six-pin pattern for phase, neutral, and protective earth conductors, helping cable routing stay orderly in tight machine sections. A smooth shaft minimizes fretting on clamp couplings during repeated starts and stops, which suits direct-coupled arrangements that depend on good concentricity. The assembly weighs only 2.9 kg, easing installation on small-to-medium gantries or articulated joints while keeping moving mass lower for faster directional changes.
