RESISTORS

Motor Starting & Control Resistors

Resistor systems for starting and speed-control duties in wound motors, squirrel-cage motors and industrial drive applications.

MOTOR STARTING / RESISTOR CONTROL

MOTOR
STARTING DUTY → RESISTIVE
CONTROL → DRIVE
OPERATION

Conceptual functional diagram; resistor duty depends on motor and drive selection.

TECHNICAL OVERVIEW

Purpose and operating principle.

LMZ motor starting and control resistors are selected according to motor power, rotor current and voltage, required starting torque, number of speed steps, desired starting time and duty cycle.

KEY FEATURES

Application-driven characteristics and selection criteria.

Applications include overhead cranes, lift trucks, machine tools and conveyors.

Used in cement plants, industrial controls, steel mills, ships and submarines.

Designed and tested according to applicable IEC and IEEE requirements.

Suitable for wound motors, squirrel-cage motors and induction motors.

Stainless-steel grid or resistance-alloy elements with durable construction.

Designed for reliable performance in heavily polluted industrial environments.

RESISTOR SYSTEMS

Electrical and thermal duty define the final resistor configuration.

LMZ resistor systems are selected around the network, current, voltage, thermal duty, operating cycle and environmental requirements of the application.
