Mechanical presentation All our brake motors can be set up to operate in the configurations shown opposite. Due to the weight of some motors, the B5 and B14 mountings would have to be confirmed by Leroy Somer. V1 - V5 mountings: Please consult Leroy Somer for 2-disk brakes. V3 mounting: Not possible for 2-disk brakes. B14 - B34 - V18 - V19 mountings: Restricted to LS160 MP, MR and LR. Motors with horizontal axis IM B3 IM B5 Mechanical protection The degree of protection for standard drip-proof motors (PLS or PB) is IP 23. The degree of protection for standard TEFV motors (LS - LSMV - FLS -...

Motor terminal box In standard versions, the terminal box is mounted on top of the motor (position A), with the cable gland on the right (1) as viewed from the drive end. Due to the symmetrical construction of the terminal box, it can be placed in any of the four directions, except position 2 on flange-mounted motors. Connection Standard connection to the stator - Single-speed motor Connection via 6 terminals. - Multi-speed motors • 2 separate speeds Connection via 2 x 3 terminals, 3 terminals per speed. • Dahlander connection Connection via 6 terminals. Standard connection to the rotor of slip-ring...

Characteristics Characteristic values Parameter Torque and current curve according to speed (Rated) (Synchronous) Type of rotor Aluminium rotor - ALU This is the most suitable type for continuous duty (S1, S2, S9 and S10) because of its optimum efficiency and power factor. However, in certain cases it can be used for intermittent duty. DP rotor This is the ideal rotor for periodic operation, since the starting torque is high whereas the current is low. It also reduces the torque drop of the aluminium rotor. This is the standard rotor used for intermittent duty motors and for 2-speed motors...

Df = braking torque Cr = resistive torque NS = synchronous speed DC = regenerative braking EF = reversal General The braking torque is equal to the torque produced by the motor, increased by the resistive torque of the driven machine. Cf = Cm + Cr Cf = braking torque Cm = motor torque Cr = resistive torque Braking time, i.e. the time required for an induction motor to change from speed N to stop, is calculated by the formula: T = n ■ J - IN f 30 ■ Cf(av) Tf (in s) = braking time J (in kgm2) = moment of inertia N (in min-1) = speed of rotation Cf (av) (in N.m) = average braking...

Operating factor Expressed as a percentage, this is the ratio of the motor power-up time during the cycle to the total cycle time, provided that the total cycle time is less than 10 minutes. Starting class Class = N = Nd + K.Nf + K'.Ni Nd: number of complete starts per hour Nf: number of electrical braking operations (deceleration) per hour Ni: number of pulses (incomplete starts up to a third of maximum speed) per hour Constants K and K' have the following values: cage motors: K = 3 K' = 0.5 slip-ring motors: K = 0.8 K' = 0.25 An electrical braking operation is defined as an operation...

D.C. brake, FCPL series, 65 to 2400 Nm, separate power supply by rectifier or doping device depending on size. It can be mounted on IP 23 or IP 55 cage rotor or wound rotor motors. Brake protection Standard version IP 44. Brake protected by a steel cover. Conditions of use There are two types of coil, one for continuous duty (S1) and one for intermittent duty (S3). When ordering, it is essential to specify the type of duty, as well as the number of starts per hour and the operating factor. Options Brake voltage (20 V, 100 V, 200 V). Release by a lever (DLRA). Brake release indicator. Lining wear...

* Operation with CDF device. (1) Can operate without a CDF device. The maximum air gap before adjustment is limited to 1.2 mm. 1) Description When stationary, the coil 9 is not energised, the disk 15 sliding on a splined sleeve is pressed between the armature 11 and the plate 8 by action of the springs 28. The motor rotor rotation is stopped. The air gap is between the yoke 9 and the armature 11. When the coil 9 is energised, the armature 11 is attracted, the springs are compressed, the disk 15 and the rotor are released. On braking, disconnection of the current eliminates the magnetic field,...

braking - FCPL 40 - 1 disk: - 35 kJ 3) Thermal capacity of brake Overheating of the brake and its coil is the sum of the losses caused: - by Joule effect in the coil - by friction when braking or starting the motor when the brake is still applied. 3-1) Losses caused by Joule effect For a constant supply voltage, the current in the coil is constant (I = U/R). As a result, the number of starts has no effect on overheating of the coil, only the operating factor is important (see 5-1-a). 3-2) Losses caused by friction a) Thermal capacity on non periodic b) Thermal capacity on periodic braking...

FCPL 60 - 2 disks: The brake release time is the same as for the 1-disk FCPL set to half the torque of the 2-disk FCPL. These values are given for a rectifier power supply. FCPL 88 - 1 or 2 disks: - ta = 150 ms b) The tolerance on the voltage supply The tolerance on the supply voltage to the coil terminals is ± 10 %. A reduced power supply increases the response time. The CDF doping device helps to avoid the effects of supply voltage fluctuations. c) The size of the air gap The brake response time depends on the size of the air gap setting. This time can be multiplied by 3 when the air gap is...
