Single Phase Induction Motor Types

Single Phase Induction Motor Types: Single Phase Induction Motor Types – As far as normal running is concerned, a single winding is sufficient. But all motors must be self start. The auxiliary winding is provided to produce finite torque at standstill and is displaced in space with respect to the main winding. Current in second …

Eddy Current Drives

Eddy Current Drives: Eddy Current Drives consists of an eddy current clutch placed between an induction motor running at a fixed speed and the variable speed load. Speed is controlled by controlling dc excitation to magnetic circuit of the clutch. Since motor itself runs at a fixed speed it can be fed directly from ac …

Current Regulated Voltage Source Inverter

Current Regulated Voltage Source Inverter: Current Regulated Voltage Source Inverter operates with current controlled PWM. In current controlled pulse-width modulation, machine phase current is made to follow a sinusoidal reference current within a hysteresis band. Fig. 6.48(a) shows a sinusoidal reference current i*A = Im sin ωt. Two bands, separated from i*A by an amount Δl, are shown in …
