Pittman unveils Series 8000 Brush DC Servo Motors

AMETEK Technical & Industrial Products (www.ametektip.com) announces that its Pittman® “Series 8000” brush-commutated DC motors, which features a seven-slot skewed armature design, offers reduced reluctance torque (or magnetic cogging) while providing quiet and smooth operation.

This new range of motors provides high reliability and performance to power applications that range from medical and data storage equipment to automation and semiconductor processing machinery.

Offered in three different lengths – 2.070 inches, 2.195 inches and 2.445 inches – the motors have the ability to deliver up to 16.8 oz-in peak torque and up to 9020 RPM of speed at continuous torque and rated voltages for standard motors. In addition, the motors’ voltage, speed, torque and current can be varied to meet the specific needs of various applications.

The standard features of the models include heavy gauge steel housing, neodymium magnets, two-pole stator, copper graphite brushes and silicon steel laminations. To promote long brush life as well as optimum concentricity, the motors’ commutators have been diamond turned after armature assembly. The windings are also resin-impregnated to provide increased reliability in incremental motion applications.

Meanwhile, the modular construction of the motors allow the assemblies to be customised with optical encoders, alternative brush materials, timing belt pulleys, cables, brakes, modified shafts, connectors and RFI suppression to satisfy various application demands. The motors can also be fitted with spur or planetary gearboxes as specified.

Pittman 30mm Brush DC Motor

New Pittman® brand 30mm brush-commutated DC motors integrate high-energy bonded neodymium magnets for maximized power density and an optimized magnetic field profile and 7-slot straight armature to minimize cogging. The motors additionally feature a large diamond-turned commutator and copper-graphite brushes to deliver high current capacity and long-life operation.

These Series 8540 brush DC motors offering high torque-to-size performance provide ideal solutions to power data storage and medical equipment and business machines, among other industry applications.

The motors (1.181 in. diameter) are available in three standard lengths (2.080 in., 2.552 in., and 3.025 in.). They can achieve continuous torque up to 9.3 oz-in. and continuous power up to 43W, depending on model, and peak torque up to 78.7 oz-in and speeds up to 6440 rpm at continuous torque for standard motors at rated voltages.

Their balanced armature minimizes noise and vibration; large pre-loaded and heavy-duty ball bearings and supports promote high shaft-load capability; PC board brush card with integral surface mount components easily incorporates electrical noise suppression; and an integral connector header allows for custom leadwire configurations.

A modular design for these motors accommodates gearboxes, encoders, and brakes using adapter plates and shaft extension modifications. Motors can further be customized to satisfy particular application requirements.

Pittman® I Series’ Brushless DC Servo Motors

KENT, OH — Pittman® brand “I Series” brushless motors equip machine designers with a family of motor solutions created for commercial and light-industrial OEM applications. Motors are available in various sizes offering a wide range of performance capability from 40 Watts to 1700 Watts continuous. Brushless technology delivers extended service life, efficiency, improved performance, and superior machine control.

The I Series motors were developed using the latest magnetic tools and materials. Their magnetic core is optimized to favor power density and efficiency while minimizing cost. The winding system allows for a wide range of operation on machine bus voltages from 12 VDC to 325 VDC. The choice of materials, including bearings, Hall devices, and insulation promote extended service life.

These small and powerful motors are available in NEMA frame sizes 17, 23, 34, and 56 and in multiple lengths for each. Depending on model, they can provide continuous stall torque from 0.117 Nm to 6.6 Nm (1 lb-in to 58 lb-in) and peak torque from 0.35 Nm to 19.7 Nm (3.1 lb-in to 174 lb-in). Rated speeds for this family of motors range from 3000 RPM to 12000 RPM.
