42mm Diameter 775 Brushed DC Motor

This 775 brushed DC motor is designed for 3–24V systems where you select between 18V and 24V windings, then size your driver and mechanics using a full curve table from no-load through max efficiency, max output, and stall.

Key Features

This model is a 775 brushed DC motor platform defined by its Φ42×L67 envelope and a complete operating-point table, making selection straightforward when current limits and torque growth toward stall must be planned up front.

  • Fixed Φ42×L67 envelope supports standard 775 motor packaging
  • Two winding options (18V / 24V) separate voltage architecture and current/torque behavior clearly
  • Full operating-point table (No Load / Max Efficiency / Max Output / Stall) supports selection by real working region
  • Stall current and stall torque define the boundary for jam events and driver protection strategy

Why Choose us

SLW Motor Highlights

  • Full Curve Table Enables Real Working-Point Selection

    You can size the motor around max-efficiency or max-output regions instead of relying on only no-load RPM.

  • Winding Choice Changes Current Stress Dramatically

    The 18V and 24V options show very different current levels across the curve, which directly affects driver sizing and wiring margin.

  • Torque Growth Toward Stall Sets Mechanical Risk

    Stall torque values define what the system must survive at jams and hard stops, which drives coupling choice and stop design.

  • High-Current Regions Require Protection Planning

    Max output and stall currents are large, so current limiting, thermal strategy, and fault recovery should be designed early.

Beyond the Standard: Performance Customized

  • 01
    Winding Choice by Supply Rail and Peak Current Limit
    We start from your rail voltage and allowable peak current, then select the winding so you avoid forcing fit through heavy PWM or overvoltage.
  • 02
    Working-Point Lock-In at Max Efficiency
    We anchor selection around your steady operating region first, then validate that your application doesn’t live near stall.
  • 03
    Current-Limit Strategy for Max Output and Stall
    We define current limiting and recovery logic early because current rises steeply from efficiency point toward max output and stall.
  • 04
    Torque Boundary Planning for Coupling and Hard Stops
    We treat stall torque as a boundary condition and confirm couplings, geartrain, and end-stops can tolerate the worst-case torque.
  • 05
    Variant Strategy Using One Φ42×L67 Platform
    If you plan multiple SKUs, we keep the 775 mechanical platform constant and differentiate variants by winding and operating point.

FAQ

Frequently Asked Questions

The following questions focus on winding selection, working-point planning, and stall protection to help you confirm 775 motor fit quickly.

How do I choose between the 18V and 24V versions quickly?
Match your supply voltage first, then compare max-efficiency speed/torque to your steady operating point, and finally confirm stall current fits your driver limit.
Which table section should I use for normal operation planning?
Use Max Efficiency to estimate steady current and heat behavior, then use Stall only as a boundary for fault events.
Why does stall matter if I avoid stalling in normal use?
Stall defines what happens during jams and hard stops, which drives driver protection, wiring, and mechanical durability.
What should I share so you can shortlist the right option?
Share your supply voltage, target RPM, load torque estimate, duty cycle, and driver current limit.
Is it suitable for repeat production across variants?
Yes. You can standardize the Φ42×L67 platform and differentiate variants mainly by winding and operating point.
