Webb28 juni 2024 · Experimentally the α cells had a slower decay time constant. For the mixed mode oscillation case (0 < w = m/n < 1), θ α completed fewer cycles than θ β. When θ α ran less than a 2π cycle while θ β completed a 2π cycle (f k+1 (θ α) − f k (θ α) < 2π), the decay rate was fast. Otherwise, the decay rate was slow. Therefore, we ... Webb12 juli 2016 · Efficiency: Motor runs more efficiently than fixed decay modes. This is achieved by maximizing the slow decay as much as possible and keeping fast decay to a minimum. Slow decay is more efficient than fast decay. Hence better efficiency is attained. Production risk management: Makes it easier to manage supply chain motors.
WebbIn 'slow decay' mode, the current flows through the two bottom FETs, which are on, and the motor voltage is near zero. The only voltage available to reduce current in the inductance is the voltage drop on the motor resistance and the FET resistance. Webb19 juni 2024 · Slow decay (motor pins shorted during PWM off) runs much better on the other hand. Low-load speed is almost linear with the duty cycle, and there's high torque …
Webbautomatically selects the current decay mode, Slow or Mixed. In Mixed decay mode, the device is set initially to a fast decay for a proportion of the fixed off-time, then to a slow decay for the remainder of the off-time. Mixed decay current control results in reduced audible motor noise, increased step accuracy, and reduced power dissipation.

There are a couple of reasons: 1) The current ripple is less; more torque is available 2) The power losses are lower. The power through the FETs is typically less than the power through the body diodes.
