Speed Variation Magnetic Powder Brake Training Bench Educational Equipment

ZE5109C Speed Variation Magnetic Powder Brake Training Bench Educational Equipment

I.Overview

This bench can be used to study a drive solution for an asynchronous

motor, by simulating various types of mechanical load called constant,

proportional or quadratic torque (pump, fan, hoist etc.).

A switch can be used to simulate simple breakdowns to make use of the

Altivar diagnostic information.

II.Description

The bench is mounted on a frame with locking castors.

It consists of:

1 x 1.5 kW asynchronous motor with inertia wheel and powder brake

1 x 1.5 kW 400 V Altivar 71 drive with braking resistor

1 TSX Micro PLC for controlling various types of load

1 drive control sequence (selector switches and indicator lights)

Measuring points on safety sockets for reading the following

information:

_ AC supply voltage and current

_ motor voltage and current

_ motor temperature (PT100 probe)

_ speed feedback voltag
