The N2300 series of brushless DC motors with integrated drive electronics offers distributed control capability and simplifies machine design, product selection and purchasing.
Pittman has extended its range of brushless DC motors with integrated drive electronics, adding the Elcom ST N2300 series.
The new series is available as part of the PittmanExpress fast delivery programme and the complete range will be featured at the Drives and Controls 2003 Show on stand D120.
By combining both drive and commutation electronics within the motor housing, the N2300 series offers distributed control capability and simplifies customers' machine design, product selection and purchasing.
Other advantages include less complex wiring with increased noise immunity as well as easy installation with lower setup costs and improved serviceability.
Utilising internal hall sensor feedback for linear speed-torque characteristics, high starting torque, and variable speed control, the N2300 series offers a complete solution for commutation and motor control using an external 24V DC supply (+/-6V) with continuous current capability up to 6A.
The adjustable control loop maintains a constant speed via an analogue input signal irrespective of load/torque variation.
Speed is linear over an input range of 1 to 4V and directional input and tacho output signals are included.
Shaft speeds as low as 100rev/min are possible with the standard integrated electronics, depending on load conditions.
Elcom ST brushless motors are available in four lengths from 58 to 95mm and feature high-energy neodymium-iron-boron magnets for maximum performance.
Speeds up to 8000rev/min and continuous torque to 345mNm can be achieved (up to 525mNm with heatsink).
Long-life applications served include medical imaging, diagnostic devices, pumps and others demanding high performance.
Standard mounting configuration is NEMA 23, however the modular design facilitates easy motor customisation as with all Pittman motors.
