答案是大脑,而大脑作为神经系统的最上端,需要靠神经末梢与肌肉相连传递信号,完成肌肉的收缩发力。下图是神经末梢传到肌纤维的示意图,神经与肌肉连接的部位,称作“运动单位”(motor unit)。 (运动单位的模拟图) 需要注意,速度越快的动作,能激活的运动单位越少,也就是能调动的肌肉越少,自然发力率越低。 研究发现,快...
1.When should you use a motor starter? Starters are used to protect DC motors from damage that can be caused by very high current and torque during startup. They do this by providing external resistance to the motor, which is connected in series to the motor's armature winding and restric...
What is an Electric Vehicle? An electric vehicle (EV) is a car that runs entirely or partially on electricity instead of gasoline. The electricity is stored in reusable batteries and used to power an electric motor that turns the wheels. Electric vehicles are categorized as follows: Battery Ele...
It’s the most primitive version of the electric motor where rotating torque is produced due to the flow of current through the conductor inside a magnetic field. The rest are all AC electric motors and are driven by alternating current, for, e.g., the synchronous motor, which always runs...
The American Honda Motor Co. offers these two warranties along with several more. The breakdown of Honda’s warranty offering for its new vehicles is as follows. New Vehicle Limited Warranty If you’re purchasing a new Honda, you automatically receive a New Vehicle Limited Warranty, which covers...
For both permanent magnet and variable reluctance stepping motors, if just one winding of the motor is energized, the rotor (under no load) will snap to a fixed angle and then hold that angle until the torque exceeds the holding torque of the motor, at which point, the rotor will turn...
Principle of DC Motor When a current-carrying conductor is placed in amagnetic field, it experiences a torque and has a tendency to move. In other words, when a magnetic field and an electric field interact, a mechanical force is produced. TheDC motorordirect current motorworks on that prin...
The general equation for motor torque is a function of the single-phase motor torque and the current flowing through each of the three phases, represented as follows: Equation (1) As stated above for trapezoidal drives, current is only flowing in two of three phase...
