DC Braking • An induction motor with high-inertial load can also come to a quick stop by circulating dc current in the stator winding – any two stator terminals can be connected to a dc source – the dc current produces stationary N,S poles in the stator • the number of stationary poles are the same at the number of rotating poles normally produced with ac currents – as the rotor bars
Braking Methods of 3 Phase Induction Motor – Electrical Edition – When the induction motor runs above the synchronous speed, relative speed between the conductors and air gap rotating field reverses, as a result the phase
Duties of induction motors 3/63. Duties of induction motors3/65 3.1 Duty cycles Unless otherwise specified, the rating of the motor will be regarded as its continuous maximum rating (CMR), defined by duty S 1 as noted below. But a machine is not always required to operate at a constant load. Sometimes it must operate at varying loads, with a sequence of identical operations, involving starts

2/12/2016 · It sounds like the braking of the induction motor is pulling more current to the induction motor and the stepper drive lost current control. This is one of the key factors to consider when a stepper driver is designed. Please refer to the circuit diagram on page H-38 (electronically page 5) of our general catalog linked below:
