Features: 17-bit and 23-bit absolute photoelectric encoder, with high-end and high responsiveness;Speed: Good high-speed performance, generally the rated speed can reach 3000 rpm, maximum speed can reach 6000 rpm;Adaptability: Strong overload resistance, can withstand a load equivalent to three times the rated torque, especially suitable for situations with sudden load fluctuations requiring rapid start;Stability: Smooth operation at low speed, no step operation phenomenon occurs at low speed operation, unlike stepper motors. Suitable for occasions with fast response requirements;Timeliness: The dynamic response time of motor acceleration and deceleration is short, generally within a few tens of milliseconds;Comfort: Heat and noise are significantly reduced.Product Specifications:Model40BST-M00130 (Standard)40BST-M00130Z (With Brake)40BST-M00330 (Standard)40BST-M00330Z (With Brake)Rated Power (W)5050100100Rated Torque0.159 N·m / 1.62 kcf·cm0.159 N·m / 1.62 kcf·cm0.318 N·m / 3.25 kcf·cm0.318 N·m / 3.25 kcf·cmDetent Torque0.159 N·m / 1.62 kcf·cm0.159 N·m / 1.62 kcf·cm0.318 N·m / 3.25 kcf·cm0.318 N·m / 3.25 kcf·cmMax Instantaneous Torque0.56 N·m / 5.71 kcf·cm0.56 N·m / 5.71 kcf·cm1.11 N·m / 11.3 kcf·cm1.11 N·m / 11.3 kcf·cmRated Speed (rpm)3000300030003000Max Speed (rpm)6000600060006000Rated Current (A)0.77 (0.86 with oil seal)0.77 (0.86 with oil seal)1.18 (1.24 with oil seal)1.18 (1.24 with oil seal)Detent Current (A)0.690.691.11.1Max Instantaneous Current (A)2.502.503.923.92Torque Constant0.2325 N·m/A / 2.372 kcf·cm/Asame0.2885 N·m/A / 2.944 kcf·cm/AsameBack-EMF Constant24.37×10⁻³ V/r/minsame30.23×10⁻³ V/r/minsameResistance (Ohm)60.5460.5431.7131.71Inductance (mH)53.3853.3837.137.1Mechanical Time Constant (ms)2.963.171.852.11Electrical Time Constant (ms)0.8820.8821.171.17Rotor Inertia0.0288 gf·cm·s²0.0309 gf·cm·s²0.053 gf·cm·s²0.060 gf·cm·s²Rated Torque to Inertia Ratio9.128.5119.8817.46Outline Drawing:Technical Specifications / Features:17-bit and 23-bit absolute photoelectric encoderHigh-end, high responsivenessRated speed: 3000 rpm, max speed: 6000 rpmStrong overload resistance (up to 3x rated torque)Stable low-speed operation, no step operation phenomenonShort dynamic response time (tens of milliseconds)Reduced heat and noise
