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.
