Motor Shaft Couplings CP35 & CP45
The motor shaft couplings by MCP provide a reliable mechanical link between motors and measuring devices such as torque sensors or tachogenerators. Each coupling set includes two precision-machined metal hubs and a polyamide cross slide block that compensates for slight shaft misalignment while transmitting torque smoothly.
Overview
The CP35 and CP45 couplings are designed for MCP laboratory systems where accurate alignment between motor shafts and measuring instruments is essential. The modular structure ensures quick installation and safe operation during torque and speed measurement experiments.
Key Features
- Two metal hubs with a central polyamide cross block
- Absorbs small axial and angular misalignments
- Ensures stable torque transmission between motor and sensor
- Available in multiple shaft diameters for MCP motor series
- Compact, durable, and easy to mount on test benches

Applications
- Connection between MCP motors and torque sensors (TSP Series)
- Coupling of motors with tachogenerators (TG Series)
- Integration in laboratory test benches and educational motor systems
- General use in low-power motor assemblies (≤1000W)
Technical Specifications
- Construction: metal hubs with polyamide cross block
- Outer diameters: 35 mm (CP35), 45 mm (CP45)
- Shaft diameters: 12–24 mm (depending on model)
- Compatible motors: 120W–1000W MCP DC/AC motors
Operation Notes
- Ensure shaft diameters match before installation.
- Do not overtighten fixing screws; allow minimal play for alignment.
- Lubrication not required; polyamide insert operates dry.
- Inspect coupling before high-speed operation for wear or cracks.
Summary
The CP35 and CP45 couplings form a compact and reliable link between MCP motors and measurement devices. Designed for precision, they ensure smooth torque transmission and mechanical safety in laboratory environments.
