Char-Lynn‚ Hydraulic Motors Introduction For the past 45 years, the Char-Lynn®‚ brand has been recognized as the industry leader in low-speed, high-torque (LSHT) hydraulic motor technology. The name Char-Lynn was coined by one of the original pioneers in the hydraulic industry, the late Mr. Lynn Charlson. The hydraulic motor designs developed by Lynn Charlson and his team use what is termed as the Orbit principle. This principal is the center of the designs pioneered by the Char-Lynn team and is based on the fact that a gerotor or Geroler®‚ star orbits multiple times (typically 6 to 8 times depending...

Circuits Circuit Design Considerations Hydraulic Circuit Open Loop Circuit Closed Loop Circuit Hydraulic drives can be divided into two basic types: 1) Traction Drives and 2) Non-Traction drives. Traction drives (also referred to as propel drives) are used to propel a wheeled or track-driven vehicle. Non-traction drives (also referred to as work drives) are used for some other vehicle function such as a winch, auger, conveyor or rotate function for a boom or crane. In an open loop circuit, oil is returned to a reservoir before returning to the motor. The motor/ pump circuit is open to atmosphere....

Design Flexibility Char-Lynn motors are truly built for high torque low speed. A lot of power is derived from this small package. This power advantage provides the designer with a product that can be used for overall compactness in addition to taking full advantage of the high pressure ratings typical of present day hydraulic components. Char-Lynn hydraulic motors allow the designer to put the power where it is needed. Furthermore, the motors can be mounted directly on the driven device away from the original power source which eliminates the need for other mechanical linkages such as chains,...

Motor Application Information Vehicle Drive Calculations Step One — Calculate Motor Speed (RPM) RPM = vehicle speed (kilometers per hour) vehicle speed (miles per hour) rolling radius of tires (meter) rolling radius of tires (inch) gear reduction ratio (if any) between motors and wheels. If no gear box or other gear reduction devices are used G = 1. If vehicle speed is expressed in m/second, multiply by 3.6 to convert to KPH. If vehicle speed is expressed in ft./second, divide by 1.47 to convert to MPH. Step Two — Determine Rolling Resistance Rolling resistance (RR) is the force required to propel...

Motor Application Information Vehicle Drive Calculations Step Six — Total Tractive Effort Step Nine — Motor Radial Load Carrying Capacity The tractive effort (TE) is the total force required to propel the vehicle and is the sum of the forces determined in Steps 2 through 5. When a motor is used to drive a vehicle with the wheel mounted directly on the motor shaft or rotating hub, the Total Radial Load (RL) acting on the motor shaft is the vector summation of two forces acting at right angles to each other. TE = RR + GR + FA + DP (Kg. or lb.) Drawbar pull desired Force required to accelerate Force...
