Reliability and MaintenanceThe behaviour of torque and horsepower with respect to speed partially determines the requirements of the motor-drive system.This torque formula implies that the torque is proportional to the horsepower rating and inversely proportional to the speed.We can categorize drive applications by their operational torque requirements: 1. Constant Torque Loads 2. Constant Horsepower Loads 3. Variable Torque Loads where torque is the am在nrcan.gc.ca上查看更多信息

Motor Efficiency and Power Factor

2012-1-30  divided by motor efficiency. Rated power depends on class of motor (which considers intended duty). Industrial grade motors usually are rated for continuous duty. Motor efficiency requirements are set by 1992 Energy Policy Act (EPACT), primarily for

How to Calculate Cost of Electricity for Electric Motor

The 3 phase electric motor is usually a large piece of equipment that uses a “polyphase” circuit to draw heavy power loads at relatively low voltages. This improves power line efficiency and provides the smooth power flow required by many such motors. The cost of electricity for electric motor 3 phase operation is ...

Calculations Simple Electric Motors

Usually for small motors maximum power is at 50% of stall torque (approximately 50% of no load speed). Maximum efficiency may be 10-30% of motor stall torque (70-90% of no load speed). While it is technically better to follow the same format and create similar curves for your motor it is not absolutely necessary for a good science project.

Motor Sizing Calculations

Selection ProcedureTorqueSpeedThe first step is to determine the drive mechanism for your equipment. Some examples are direct rotation, a ball screw, a belt and pulley or a rack and pinion. Along with the type of drive mechanism, you must also determine the dimensions, mass and friction coefficient, etc. that are required for the load calculation: 1. Dimensions and mass (or density) of load 2. Dimensions and mass (or density) of each part 3. Friction coefficient of the sliding surface of each moving part Next you will need to determine th

Motor Sizing Principles - Dublin Institute of Technology

2008-2-14  Accelerating Torque: = T motor-Tload In order for the motor to start the load and get it up to correct speed then the motor torque must be higher than the load torque at zero speed (starting torque) and at every speed up to the desired operating speed. If the load torque ever exceeds the motor

The load carriers are filled by a newly electrified 'pre-crusher,' which is in turn stocked with rocks by a 70-ton dual-powered excavator. This excavator plugs into the electric grid to drive an electric motor for its main task of scooping rocks, while using a standard diesel engine for its minimal movements around the quarry.

Unlike consumer motor vehicles, which are comparable by their year and mileage — who wants to buy a 1995 vehicle with $750K miles on it? — agriculture and farming equipment is usually rated by service hours. When considering a used heavy equipment value guide, the age or mileage of the equipment shouldn’t be a determining factor.
