Main Features and Advantages
The fundamental strength of the 1361-NO61-2-5 is that it provides dependable DC motor control in a compact, single-phase package. Many small and medium machines do not justify a three-phase supply or a modern DC converter, yet still require smooth acceleration, controlled stopping and stable speed under load. The Bulletin 1361 platform was developed for exactly this category, and the 1361-NO61-2-5 inherits that application focus.
Regulation flexibility is a key advantage. The 1361-NO61-2-5 can regulate armature voltage, motor speed or current/torque depending on the selected feedback and the application requirement. Armature-voltage regulation is sufficient for many simple constant-load machines. Where better load regulation is needed, tachometer-generator feedback can be used to provide closed-loop speed regulation. Current/torque control supports applications where controlled starting torque or tension is more important than exact speed.
The 1361-NO61-2-5 is also straightforward to integrate with existing machine controls. It can be operated from local start/stop and speed-reference devices, including a speed/torque potentiometer, while ModOps support preset-speed, jog-speed, remote operator control stations and auxiliary pilot contacts for interlocking alarms and indicators. This allows the drive to be added to a machine without redesigning the control panel.
Serviceability is another practical benefit. The Bulletin 1361 design separates the power components, control and regulator electronics, terminal/fuse board and optional ModOps. For the 1361-NO61-2-5, this means that a failed control board, power bridge, contactor or field circuit can often be isolated and repaired or replaced at board level. It also means that exact replacement matters: the motor voltage class, field configuration, current rating and fitted ModOps must all be confirmed before a substitute is fitted.
