Starting Current Gearless Mill Drive
Gearless mill drives Grinding ABB
Our GMD eliminates all mechanical components of a conventional mill drive system, such as ring-gear, pinion, gearbox, coupling, motor shaft and motor bearings: By mounting the rotor poles directly onto the mill, the mill itself becomes the rotor of the gearless motor.

Ring-geared mill drives Grinding ABB
Soft-starting Smoothly starts the mill without mechanical shocks and limits the current drawn from the network, avoiding unexpected downtime due to voltage unbalances. Frozen charge remover Avoids human contact with the mill and speeds up the re-start of the system after the frozen charge is detected.

Revolutionary Drive Controller for Gearless Mills
On big milling applications, mainly above 10 MW, gearless mill drives (GMD) are used. Figure 1. Mining process and Mill-Motor location in the concentrator. A GMD is built on three major components: − Ringmotor (Figure 2); − Frequency converter with controller, where the frequency converter (Figure 5) has a Cycloconverter for the stator current
TECHNICAL AND COMMERCIAL BENEFITS OF GEARLESS MILL DRIVES
Gearless mill drives are a well established solution for grinding The current in each phase is controlled by a 12-pulse ranges from the starting point up to the drive operational range. In this range, the output has a constant torque capability with varying power.
Gearless Mill Drive Sales Rev Up to Meet Demand
Gearless mill drives are becoming the drive system of choice on large AG, SAG and ball mill installations for new Synchronous motors have a high inrush starting current—400% to 600% of nominal current. The starting torque depends on the motor design and can’t be adjusted later on.
Motor Starting & Running Current Calculator
Starting & Running current are the three important factors for the rating of AC induction motor. Starting Current, sometimes abbreviated as I start in electrical engineering, is a measure or rating of how much current required for a single or three phase AC motor to get started. It's generally, four times of running current.

Gearless conveyor drives (GCD) for high power ABB
ABB’s gearless conveyor drives (GCD) enable the design and construction of high torque conveyors which go to the limit of belt strengths and pulleys. Synchronous motors (2.5 9MW, 50-60rpm / 400 1700kNm) are embedded onto a special base frame which allows to transport the motor in a piece, to perform shortest installation time as well as quick and easy alignment of the motor to the pulley.
