Rotor construction enables rotational speeds to 8,000 rpm, and 3 Hall sensors provide rotor position feedback. Housed in aluminum, series features 3-phase stator with 6-slot silicon steel laminations; 4-pole rotor with neodymium ring magnets; and ABEC ball bearings with dynamic load ratings up to 390 lb.

Original Press Release:

Pittman® Elcom ST® 'Series 1300' Brushless DC Servomotor Delivers More Power In Smaller Package

New PITTMAN® brand ELCOM ST® "Series 1300" slotted brushless DC servomotors can deliver more power in a smaller and cost-effective package to maximize design flexibility and satisfy application requirements where space may be minimal.

Despite their small size (1.3"/33mm diameter), these brushless DC motors can achieve peak torque from 12.6 oz-in to 54.3 oz-in and continuous torque from 5 oz-in to 9 oz-in, depending on model. Robust rotor construction allows rotational speeds up to 8000 RPM.

Three Hall sensors are incorporated as standard components to provide rotor position feedback for electronic commutation. Other standard features include 3-phase stator with 6-slot silicon steel laminations; 4-pole rotor integrating high-energy neodymium ring magnets for optimized motor performance; and large ABEC ball bearings with high dynamic load ratings (up to 390 lbs.) and shielded to protect against contaminants.

PITTMAN "Series 1300" brushless DC motors are available in three lengths (1.5", 2", and 2.5"); housed in precision-machined aluminum to promote lightweight designs; and include integral front-endbell. Optional square flanges can be specified for NEMA 14 mounting.

Motors can further be customized with a wide range of components to meet application demands, including planetary or spur gearboxes and optical encoders, among others.
