Overview
The Graham Motors and Controls 176B3003 Cycletrol DC motor speed controller is a proven industrial-grade DC drive engineered for applications demanding rapid cycling and precise motor speed regulation. As part of Graham Motors and Controls’ Cycletrol Series, this controller delivers reliable variable-speed control with minimal maintenance compared to traditional clutch/brake systems. The 176B3003 is ideal for machinery requiring frequent start/stop cycles and adjustable torque delivery.
Key Features
- Optically isolated digital logic inputs enable safe interfacing with switches, push-buttons, and solid-state control devices
- Adjustable current limiting provides automatic torque control and motor protection during overload or jam conditions
- Voltage-clamping MOV and RC network transient protection guards against power spikes and electrical stress on components
- LED status indicators deliver real-time visibility into controller function and operational state
- Robust aluminum chassis or NEMA 12 enclosure options suit demanding industrial environments
- Single-phase or three-phase input availability (verify configuration for your model)
Technical Specifications
The Graham Motors and Controls 176B3003 controller is engineered for DC motor applications in the fractional to 2 HP range. The Cycletrol 150 series is rated for up to 60 cycles per minute, supporting high-speed cycling demands. Input voltage options include 120 VAC and 240 VAC configurations at 50/60 Hz, with typical current ratings of 15 A. Output includes DC voltage control suitable for permanent magnet or shunt-wound DC motors. Mounting options include surface-mount and pedestal configurations to fit various installation spaces.
Typical Applications
- Packaging and labeling machinery requiring frequent speed transitions
- Printing equipment with variable-speed motor control needs
- Conveyor systems with adjustable feed rates and dynamic braking
