The work presented in this article investigates the experimental study of the effects of various operating parameters such as oil temperature, speed, sizes and the load torque on the steady-state performance of the fixed displacement bent axis motor. In this respect, five different capacities of the motor are considered. The effects of the operating conditions and the capacities of the motor on its flow and torque-losses are identified. With an increase in pressure and temperature, gaps in the hydrostatic machine vary, and it also affects the viscosity of the fluid. The outcome of them on the performance of the motor is characterized. From the test data, a mathematical model of the losses is established that consider the influence of oil temperature, motor speed, load torque, capacities of motor and the system pressure. The model has shown good agreement with the test data; the overall efficiency of the different capacities motor at three different operating temperatures is compared. Such a model may be adapted to evaluate the performance of motor over a range of operating conditions. The proposed model may be utilized by the technocrats for selecting the bent axis motor drive for a given application.

本文介绍的工作调查了各种运行参数（如油温、速度、尺寸和负载扭矩）对固定排量斜轴电机稳态性能的影响的实验研究。在这方面，考虑了电机的五种不同容量。确定了运行条件和电机容量对其流量和扭矩损失的影响。随着压力和温度的升高，静液压机中的间隙会发生变化，也会影响流体的粘度。它们对电机性能的结果进行了表征。根据试验数据，建立了考虑油温、电机转速、负载转矩、电机容量和系统压力影响的损耗数学模型。该模型与测试数据显示出良好的一致性；比较了不同容量电机在三种不同工作温度下的整体效率。这种模型可以适用于评估电机在一系列操作条件下的性能。技术专家可以利用所提出的模型为给定的应用选择斜轴电机驱动器。
