The advantages of a brushless motor over brushed motors are high power-to-weight ratio, high speed, nearly instantaneous control of speed (rpm) and torque, high efficiency, and low maintenance. Brushless motors find applications in such places as computer peripherals (disk drives, printers), hand-held power tools, and vehicles ranging from ...
The Emrax 268 is a brushless 250 volt design producing a peak of 230 kW (308 hp), 100 kW (134 hp) continuous, with an outrunner coil. It has a 98% efficiency. The low working rpm of the engine means that it can turn a propeller at efficient speeds without the need for a reduction drive.
The EM 42 is a fixed-shaft brushless DC electric motor running at 190-288 V, and drawing up to 160 A, the 42 kW motor can deliver up to 216 N.m of torque over a speed range of 160-1600 RPM with a total efficiency of 90%. Maximum continuous power is 38.5 kW, the motor weighs 29 kg, and the weight of power electronics is 10 kg.
The rating of a brushless motor is the ratio of the motor's unloaded rotational speed (measured in RPM) to the peak (not RMS) voltage on the wires connected to the coils (the back EMF). For example, an unloaded motor of K v {\displaystyle K_{\text{v}}} = 5,700 rpm/V supplied with 11.1 V will run at a nominal speed of 63,270 rpm (= 5,700 rpm/V ...
The Emrax 228 is a brushless 130 volt design producing a peak of 100 kW (134 hp), 55 kW (74 hp) continuous, with an outrunner coil. It has a 98% efficiency. The low working rpm of the engine means that it can turn a propeller at efficient speeds without the need for a reduction drive.
An industrial electric motor . An electric motor is a machine that converts electrical energy into mechanical energy.Most electric motors operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor's shaft.
Universal motors can be and are generally run at high speeds, 4000–16000 RPM, and can go over 20,000 RPM. [5] By way of contrast, AC synchronous and squirrel-cage induction motors cannot turn a shaft faster than allowed by the power line frequency. In countries with 60 Hz AC supply, this speed is limited to 3600 RPM. [7]
High-power, brushless axial motors are more recent, but are beginning to see usage in some electric vehicles. [8] One of the longest produced axial motors is the brushed DC Lynch motor, where the rotor is almost entirely composed of flat copper strips with small iron cores inserted, allowing power-dense operation.
