FP3/10 : ELECTROMAGNETIC BRAKE "BALANCE" MOUNTING

PRINCIPLE

The FP.3/10 brake provides a test load for electric motors. It is made up of a stator mounted in "Balance" and a rotor driven by the machine to be tested.

PROPERTIES

The resisting torque is proportional to the excitation current of the brake coil and practically independent of the rota-tional speed. The T f (iexc) and T f(n) curves of the brake are shown below.

MESUREMENT OF THE RESISTING TORQUE MOMENT

The "Balance" mounting allows the measurement of the resistance torque moment opposed by the brake. This measument may be performed directly by a CAP.FOR.S force sensor combi-ned with a MODMECA measurement module.

Note: MODMECA is a reference of equipment to be ordered in addition to the FP 3/10 brake.

CHARACTERISTICS

- Maximum speed: 3 000 min-1

- Supplying of the coil of the

MODMECA measurement module

- Excitation current: • rated i = 0.65 A • maximum i = 0.8 A

- Brake torque: • nominal T = 10 N.m • maximum T = 12 N.m • residual T ð 0.1 Nm at i = 0


- Didactic terminal block with Ø 4 safety terminals.

- Thermal protection by temperature probe.

- The unit is mounted on a SU.S test bed and delivered with one lifting arm and three shaft guards.

CAP.FOR.S : FORCE SENSOR

MESUREMENT OF MOTOR TORQUE IN STABLE OPERATING CONDITION PRINCIPLEAs standard, the force sensor is delive-red with powder brake. Placed at a dis-tance "d" from the pivot point, it indicates the moment of the brake resisting torque, which is the same as the torque moment of the shaft of the motor under test, providing the stable operating condition has been reached.

This force sensor has 4 strain gauges mounted as a Weasthone bridge. The variation of the applied effort induces a proportional variation of the resistance of the gauges, thus a proportional variation of the measurement signal.

CHARACTERISTICS

- Rating: 200 N

- Overload : 300N

- Supply voltage: 10V DC

- Sensitivity: 1.5 mV/V

The power supply for the bridge, the amplification of the signal, the reading and the analogue output of the torque moment image are performed by the MODMECA Measurement Module.

The sensor is connected with a DIN 7-pin cable.

CAP.CO.S : TORQUE SENSOR

MESUREMENT OF THE MOTOR TORQUE IN DYNAMIC MODE PRINCIPLEThe rotary torque sensor, mounted on the floating shaft, is inserted between the motor and the load.

It also allows the measurement of the torque moment available on the motor shaft, in transitory as well as permanent conditions. This sensor is a strain gauge device with slip-rings and brushes. It compri-ses a rotary shaft revolving on bea-rings inside a socket. The shaft has a narrow section, the torsion bar, on which the strain gauges are mounted so as to make an integral bridge.

Slip-rings and brushes provide the con-nection between the rotor and the casing.

CHARACTERISTICS OF THE SEN-SOR ALONE

- Rating: 10 Nm

- Measurement range: Tn =10Nm, overload 15Nm

- Linearity error: maximum ð 0.25% .

- Bandwidth: 500 Hz at -3dB

- Supply voltage: 10V CC

- Sensitivity: 2 mV/V

- Nominal rotational speed: 1500 min-1

- Maximum rotational speed (10min) :

3000 min-1



The connection to the machines is made by two half couplings provided with the sensor.

GENERALTo study electrical rotating machines with or without electrical drives, requires testing machines and ancillary equipment to verify that they function according to theory and at the same time recording the electrical and mechanical characteristics.

In order to achieve this, using machines and test benches from the 0.3kw and 1.5kw range, we offer a range of products for load control, measurement of electrical and mechanical values, as well as data acquisition and computer processing.

The modular concept of the products described in the following pages provides the setups necessary for the different experiments and to adapt to different levels of study.

The torque control feature which is independent of speed, in addition to the simplicity of control of this type of brake allows very easily the application of different types of industrial loads, particularly with the mechanical load simulator MOD'SIM and to verify the response of motors and motor variators under test.

MODSIM : MECHANICAL LOAD SIMULA-TION MODULE

GENERALTo study electrical rotating machines with or without electrical drives, requires testing machines and ancillary equip-ment to verify that they function accor-ding to theory. The powder brake mounted on the test benches (FP3/10 FP10/15D2 or FP15/30 depending on the power), allows an easily ajustable load. Together with the brake, MOD'SIM enables a load to be applied similar to that of the various industrial applications.MOD'SIM generates 4 torque-speed load caracteristics, as well as pulse con-trol operation with adjustable duration and cycle. Being analogue, this module is easily accessible and user-friendly.

FRONT PANEL The mechanical load simulation module comes between the tachogenerator and the powder brake of the test bench.

Inputs: the module receives speed information necessary to provide the correct "torque-speed" curves.This can be provided: - directly from the tachogenerator of the

20V or 60V at 1000min-1 range .- or from the n analogue output of the

MODMECA - 5V at 2000 or 6000min-1

mechanical measurement module.

Outputs: the module provides a suita-ble supply:- directly to the powder brake coil termi-nals of one of the 3 types FP3/10 - FP10/15D2 - FP15/30.- or to the "cde exter." terminals of the mechanical measurement module - ModMéca - which controls the resisting torque.

Powder brake control: 5 powder brake control modes are available. - Pulse torque:the braking torque varies between 2 values separately adjustable (minimum value B and maximum A+B). The period varies between 1 to 200s and the duty cycle between 0 to 100%.

- Constant torque T=B=cste :the adjustable braking torque equals B and is independant of the rotational speed.Example : lifting, conveying, cross travel...

- Torque proportional to n: T = An+B: the braking torque is proprotional to the rotational speed .Example: dosing pump, impeller ...

- Operation: T = An2+B : the braking tor-que is proportional to the rotational speed squared. Example: fan, centrifugal pump ...

- Operation at constant power : P=A=cste: the braking torque is in inverse proportion to the rotation speed (T = A n-1) which corresponds to an ope-ration at constant power. The maximum torque is limited and adjustable in order to avoid stalling of the test machine during starting. Example: turning, milling, unwinding, winding ...Note: the brake resistance torque is given by the force sensor mounted on the electromagnetic powder brake.

PRACTICAL EXAMPLES Practical examples are presented in the documentation provided with the module. - Study of a DC or AC motor speed drive with various types of static or dynamic loads applied. - Study of a speed closed-loop control in static and dynamic mode.
