Application-specific AC Drives. Our application-specific AC Drive lineup includes the CR700 for cranes and L1000A for elevators. These high-performance AC.
The Maxspeed crane control system uses adjustable speed drives to control the speed and direction of the crane motors driving the gantry, trolley, boom, cable
b)Draw the torque-speed characteristics of a separately excited DC motor during dynamic braking. c)Why regenerative braking is not possible in half controlled
In this case of negative power demand, hoist motor 34 generates AC power that is converted to DC power by power inverter 28 under the control of inverter
A variable-frequency drive (VFD) is a type of motor drive used in electro-mechanical drive systems to control AC motor speed and torque by varying motor
Crane duty motors are used for following applications in majority: Cranes & hoists: long travel drive, cross travel drive, main hoist, auxiliary hoist.
ily, SIMOCRANE offers a high-performance drive system for total control of the motion and therefore Siemens offers a broad spectrum of hoist and gantry.
Case note Regenerative AC drive improves overhead … Previous AC drives used on the crane, regenerated energy back to a brake resistor when the motor was
