E-bicycles, also known as pedelecs (pedal electric cycles) or EPACs (electric power-assisted cycles), represent a more and more popular variation of the traditional bicycle. E-bicycles feature a small electric motor that provides power to the bicycle’s drive mechanisms, reducing or eliminating altogether the physical energy normally required. As such, they are particularly useful for long bicycle trips or for traveling over difficult terrains.
The Motomea dynamometer solution works according to standards for road vehicles, including EPACs (EN 15194:2009-06) and/or PAS. The system can be used for pedelecs and for all sorts of motorized bicycles, tricycles, quadricycles, cargo-bikes, and others, with or without pedal combination.
An EPAC is a “bicycle” if:
FOUR-QUADRANT OR HYSTERESIS BRAKE
E-BIKE UNIQUE TESTING CAPABILITIES
E-BIKE BATTERY SIMULATION
MAIN SYSTEM CAPABILITIES & FEATURES
The Motomea EPAC Bicycle tester gives you the option to:
The system is designed to comply with the standard request for high-frequency emission, enabling the electromagnetic immunity test. In addition, the system includes an output function for scaled voltage, enabling automatic testing at the EMI laboratory, showing speed ripple as a function of the test frequency.
SYSTEM SUITABLE FOR:
MOTOMEA IDS – INERTIAL DYNAMOMETER SYSTEM
OVERVIEW
The motor is accelerated from stall up to no-load speed. The load used for the testing is the moment of inertia of the motor’s rotor & flywheel. From the acceleration period, the system gives the complete motor load performance, together with additional dynamic unique testing, such as ripple torque, cogging, friction, and back EMF.
Since the entire measuring time is very short (acceleration time), the motor has no time to warm up. In such a way, the motor characteristics are given at constant pre-defined temperature. The method achieves very accurate (± 0.2%) test results that are very well reproducible, regardless of the operator and independent of any brakes, especially of their additional mechanical losses. The method clearly shows the influence of the temperature on motor performance and efficiency.
The system includes a very user-friendly software, presenting the data in graphs and tables, and saving them for evaluation, comparison, quality assurance, etc.
