Haydon Kerk Pittman Launches 26mm Brush DC Motors for Precision Drives

In precision motion systems, motor selection directly determines the upper limit of system performance. Haydon Kerk Pittman's DC026C series of 26mm brushed DC motors offers engineers a reliable solution through compact dimensions and exceptional performance parameters.

The DC026C series comprises three models (DC026C-1, DC026C-2, DC026C-3) with progressively optimized specifications to meet varying load requirements.

All models support up to 48V DC terminal voltage and deliver mechanical no-load speeds reaching 10,000 rpm. This high-speed capability provides a foundation for applications requiring rapid response or high linear velocity.

• Continuous Stall Torque: Ranges from 0.014 Nm (1.9 oz-in) for DC026C-1 to 0.022 Nm (3.2 oz-in) for DC026C-3, making the DC026C-3 model preferable for applications demanding sustained torque output.
• Peak Torque: Shows more significant variation, with DC026C-1 at 0.059 Nm (8.3 oz-in) and DC026C-3 reaching 0.13 Nm (19 oz-in). This parameter is critical for overcoming initial resistance or handling sudden load changes.

The DC026C-1 model features rotor inertia of 0.00000099 kg m² (0.00014 oz-in-s²), while the DC026C-3 measures 0.0000016 kg m² (0.00000023 oz-in-s²). Lower inertia models like DC026C-1 may be preferred in applications requiring exceptional dynamic response.

Weight increases from 76g (2.7 oz) for DC026C-1 to 110g (3.7 oz) for DC026C-3, corresponding with torque output improvements. This tradeoff between performance and weight must be evaluated for space-constrained applications.

The series extends beyond basic motor functionality through comprehensive integration options:

With a 26mm diameter, these motors fit into space-limited designs. Detailed dimensional drawings facilitate precise mechanical integration.

Available performance curves and winding data enable accurate system simulations, allowing optimization of efficiency, power consumption, and output characteristics at specific operating points.

• Encoders: Provide position and velocity feedback for closed-loop control, essential for robotics, automation, and medical devices requiring high precision.
• Gearboxes: Various transmission ratios increase output torque while reducing speed, suitable for low-speed, high-torque applications like valve control.
• Brakes: Offer reliable holding force during power loss, critical for vertical motion systems or applications requiring precise stopping.

• Automation and Robotics: Small-scale, high-precision drives for compact robotic arms or AGV steering systems.
• Medical Equipment: Precision pumps, actuators, and diagnostic instrument components demanding reliability and accuracy.
• Consumer Electronics: Advanced smart home products and power tools requiring compact drives.
• Aerospace and Defense: Specialized equipment with stringent weight and reliability requirements.

Comprehensive support includes 2D/3D model downloads and motor calculation tools, streamlining the selection and design process for engineering teams.

The DC026C series combines manufacturing precision, robust performance parameters, and flexible integration options to deliver a versatile motion solution. Understanding these technical specifications in relation to application requirements enables optimal implementation across diverse industries.
