The brake engages automatically; no separate control signal is needed beyond the drive's brake-release output. ## Encoder feedback and position hold after power loss The 17-bit magnetic multi-turn encoder reports absolute position over 131,072 counts per revolution and tracks multiple shaft turns even when the system is unpowered. That eliminates the need for a homing cycle on every power-up — the drive reads the current position directly from the encoder when the bus voltage comes up. Magnetic encoder technology is inherently more tolerant of contamination than optical encoders — no glass disk to fog or scratch — which is one reason the motor carries an IP67 rating on the body. The encoder itself is sealed within the housing. ## Mounting, shaft, and mechanical interface The motor uses an Asian standard flange with a 40 mm square pilot — common on compact servo frames from several manufacturers. Four mounting holes on a 4.3 mm diameter circle secure the motor to the machine plate. The shaft is 8 mm diameter with a 25 mm length, fitted with a parallel key (3 mm key width). No second shaft end exists, so the rear of the motor is closed — no room for a manual crank or secondary encoder on the back side. Maximum radial force on the shaft is 78 N, and maximum axial force is 54 N. Exceed those limits and the bearing life drops sharply — budget a flexible coupling if the load applies side load. ## Electrical parameters for drive tuning The torque constant is 0.29 N·m/A at 40 °C, and the back EMF constant is 20.1 V/krpm. These two numbers let the drive calculate the current needed for a given torque and the voltage the motor generates as it spins. Continuous stall current is 1.1 A; peak current is 3.9 A for short-duration acceleration, delivering 1.12 N·m peak stall torque. With 10 motor poles, the electrical frequency at 3000 rpm is 250 Hz — the drive's current loop must handle that bandwidth. The single-phase input simplifies wiring in smaller panels but limits the available power compared to a three-phase supply.","metaTitle":"Schneider Electric BEH18MB0133MF5C Servo Motor, 100 W","metaDescription":"Schneider Electric BEH18MB0133MF5C Lexium 18 servo motor with brake, 100 W continuous power, 3000 rpm, 0.32 N.m holding torque, IP67, 17-bit multi-turn encoder.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Servo Motors with Brake"],"specifications":{"Depth":"101.1 mm","Range":"Lexium 18","Width":"40 mm","title":"BEH18MB0133MF5C","Height":"49.1 mm","Length":"101.1 mm","Inertia":"0.069 kg.cm²","Key width":"3 mm","Shaft end":"Parallel key","description":"BEH18 servo motor, Lexium 18, 220V,100W,M40,17bit MAG MT,brake","Encoder type":"Magnetic encoder","Second shaft":"Without second shaft end","Shaft length":"25 mm","Feedback type":"17 bits magnetic multi turn encoder","Holding brake":"With","Nominal speed":"3000 rpm, 220 V, single phase","Rotor inertia":"0.069 kg.cm²","Holding torque":"0.32 N.m","Nominal torque":"0.32 N.m, 220 V, single phase","Product weight":"0.57 kg","Shaft diameter":"8 mm","Torque constant":"0.29 N.m/A at 40 °C","Type of cooling":"Air-cooled","lifecycle_stage":"current","Continuous power":"100 W","Mounting support":"Asian standard flange","Back emf constant":"20.1 V/krpm at 40 °C","Device short name":"BEH18","Motor flange size":"40 mm","Peak stall torque":"1.12 N.m, 220 V, single phase","Maximum current Irms":"3.9 A at 0.1 kW, 220 V","Nominal output power":"100 W, 220 V, single phase","Electrical connection":"2 connectors male/female","Number of motor poles":"10","Maximum axial force Fa":"54 N","Continuous stall torque":"0.32 N.m, 220 V, single phase","IP degree of protection":"IP67","Maximum radial force Fr":"78 N","Mounting holes diameter":"4.3 mm","Continuous stall current":"1.1 A","Maximum mechanical speed":"3000 rpm","Network number of phases":"Single phase","Number of mounting holes":"2","Maximum permanent current":"3.9 A","Product or component type":"Servo motor","Speed feedback resolution":"131072 points/turn","[Us] rated supply voltage":"220 V","Ambient air temperature for operation":"0...40 °C"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/d2d91b02e6902b626570880b7e8ba96e.pdf","sourceUrl":"https://www.se.com/th/en/product/BEH18MB0133MF5C/beh18-servo-motor-lexium-18-220v100wm4017bit-mag-mtbrake/"},"ai":{"faq":[{"question":"What is the holding torque of the brake on the BEH18MB0133MF5C?","answer":"The holding brake delivers 0.32 N·m of holding torque, which is also the nominal torque rating of the motor itself.
