Operating Recommendations OIL TYPE Hydraulic oils with anti-wear, anti-foam and demulsifiers are recommended for systems incorporating White Drive Products motors. Straight oils can be used but may require VI (viscosity index) improvers depending on the operating temperature range of the system. Other water based and environmentally friendly oils may be used, but service life of the motor and other components in the system may be significantly shortened. Before using any type of fluid, consult the fluid requirements for all components in the system for compatibility. Testing under actual operating...

Operating Recommendations & Motor Connections motor/brake Precaution (continued) operation, it is necessary to bleed out any trapped air and fill brake release cavity and hoses before all connections are tightened. To facilitate this operation, all motor/brakes feature two release ports. One or both of these ports may be used to release the brake in the unit. Motor/brakes should be configured so that the release ports are near the top of the unit in the installed position. motor circuits There are two common types of circuits used for connecting multiple numbers of motors – series connection...

Product Testing Performance testing is the critical measure of a motor’s ability to convert flow and pressure into speed and torque. All product testing is conducted using White Drive Products’ state of the art test facility. This facility utilizes fully automated test equipment and custom designed software to provide accurate, reliable test data. Test routines are standardized, including test stand calibration and stabilization of fluid temperature and viscosity, to provide consistent data. The example below provides an explanation of the values pertaining to each heading on the performance...

Allowable Bearing & Shaft Loading This catalog provides curves showing allowable radial loads at points along the longitudinal axis of the motor. They are dimensioned from the mounting flange. Two capacity curves for the shaft and bearings are shown. A vertical line through the centerline of the load drawn to intersect the x-axis intersects the curves at the load capacity of the shaft and of the bearing. In the example below the maximum radial load bearing rating is between the internal roller bearings illustrated with a solid line. The allowable shaft rating is shown with a dotted line. The...

vehicle drive calculations When selecting a wheel drive motor for a mobile vehicle, a number of factors concerning the vehicle must be taken into consideration to determine the required maximum motor RPM, the maximum torque required and the maximum load each motor must support. The following sections contain the necessary equations to determine this criteria. An example is provided to illustrate the process. Step One: Determine Rolling Resistance Rolling Resistance (RR) is the force necessary to propel a vehicle over a particular surface. It is recommended that the worst possible surface type...

vehicle drive calculations Step Three: Determine Acceleration Force Acceleration Force (FA) is the force necessary to accelerate from a stop to maximum speed in a desired time. FA = Where: t = time to maximum speed (seconds) Example Step Four: Determine Drawbar Pull Drawbar Pull (DP) is the additional force, if any, the vehicle will be required to generate if it is to be used to tow other equipment. If additional towing capacity is required for the equipment, repeat steps one through three for the towable equipment and sum the totals to determine DP. Step Five: Determine Total Tractive Effort...

induced side load In many cases, pulleys or sprockets may be used to transmit the torque produced by the motor. Use of these components will create a torque induced side load on the motor shaft and bearings. It is important that this load be taken into consideration when choosing a motor with sufficient bearing and shaft capacity for the application. T tera G giga M mega K kilo h hecto da deka d deci c centi m milli u micro n nano p pico f femto a atto To determine the side load, the motor torque and pulley or sprocket radius must be known. Side load may be calculated using the formula below....
