MR158E Speed Variation Magnetic Powder Brake Training Bench Teaching Education Equipment For School Lab Electrical Laboratory 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
