Description

eBay The motor as the engineering prototype profile diameter 126.5MM the torque, speed smooth, and can be used as a general power direct drive and hassle of reduction gear so as to improve the efficiency, the core parts are implemented using metal-supported rotor bracket is made of engineering plastic as a supporting framework, can meet the requirements is not high, to power a small amount needs of the occasion, or as a teaching model demo can also be based on application strength customized metal skeleton and power, in need please contact the station customer service. The motor is a permanent magnet three-phase DC brushless motor in this circumstance, the entity needs plus purchase adaptation of the brushless motor driver to use. At the same time it is also a generator, an external force transmission (such as hydro, wind, hand, treadmill, the Stirling engine, etc.) may output a three-phase alternating current (AC), added to the three-phase rectifier Bridge can be converted into a direct-current use, to charging the battery. As a result of this motor has the advantages of simple structure, disassembly and assembly are convenient, installed in a fixed manner flexible, many a coaxial parallel access to multiple power output shaft can replace any length, is the initial product research and development, DIY in the production of various types of model toys, small generators of good choice . This product adopts the standard design of the magnetic circuit, the rotor wheel for superconducting magnet side-by-side with the stator core constituting the magnetic flux loop make full use of the electromagnetic torque, coupled with the excellent pole and slot combination magnetomotive force of the high rate of the utilization of the cogging torque is small, to maximize motor integrated performance. Stator punching Hall embedded positioning groove design, the hall element can be fine indeed measurement of rotor position, so that the three-phase winding brushless commutation more accurate, to ensure that the motor forward and reverse consistent performance. Special note: This product without the dynamic balance correction Motor high speed range may have vibration, shipment as far as possible to reduce vibration, there is no guarantee that the specific values. This product is a kind of hollow shaft design, shaft front and can be fitted with a 8 were M3 screws, convenient for you to deliver the motor installed on the rotary encoder (magnetic encoders, grating encoder, etc.), coupled with the servo driver applied to the numerical control machine tool, a robotic arm, such as intelligent application fields. But if it's not a sense of rotary encoder, this motor has built-in the hall sensor, can be an ordinary all brushless drive direct drive. This product is a engineering prototypes, due to the Long Time Running aging test, therefore, our company is not the user's specific apps. The present Motor adopts domestic bearing, if the speed is too high (greater than 3000 rpm) can lead to bearing heat, please pay close attention to its temperature rise. This motor is consistent with the corresponding driver may direct speed (potentiometer 0 ~ 5V analog voltage or PWM signal speed), thanks to its use of the multi-pole structure and Hall sensor, to ensure that its low speed conditions normal operation. Product specifications: size: diameter 126.5 * thick 36mm weight: about 0.96kg the hollow shaft: hol e diameter 23mm the stator: diameter 115 * thick 10mm the slot structure: 27 The Groove 30 is lead length: 25 ~ 30cm hall angle: with a 120-degree overview line-sequential description: green = A(U), yellow = B(V), blue = C(W) electrical parameters: speed constant (KV): 42.75RPM/V working voltage: DC12V ~ 48V no-load speed: 2052PRM @ 48V rated voltage: 48V rated power: 400W rated speed: 1570PRM rated torque: 2.5Nm rated current: 10A conversion efficiency: 86% the rated electrical parameter is estimated, specific to the measured subject, which were inserted for reference purposes only.
