A 750 W gear motor is the default answer wherever a conveyor, mixer or gate needs torque at low speed rather than raw speed – the gear stage trades speed for torque at a fixed efficiency. The KaiVoy 750 W unit is wound for 220 V or 380 V three-phase, with the reduction ratio selected to the application and B3 foot or flange mounting.
哪些是固定的，哪些由你定
| Item | 规格 | 由你确定 |
|---|---|---|
| 功率 | 750 W | Fixed – size the driven load before ordering |
| 供电 | 220 V / 380 V, three phase | 以配电柜实际为准，别赌铭牌 |
| 减速比 | 按应用选配 | 告知输出转速或扭矩，我们确认减速比 |
| 安装 | B3 卧式底脚 / 法兰可选 | Match the machine’s existing foot print |
| 可选件 | 制动器、接线盒位置、防护等级 | 保位负载与门体选制动器 |

实际工程中的选型规则
- Start from the load, not the motor: belt and roller conveyor projects, mixers and agitators, industrial doors and packaging machinery all have characteristic torque curves – state the driven machine and duty cycle, and the ratio follows.
- Ratio = speed you have / speed you need: a 750 W motor at a lower ratio runs cooler than the same motor pushed by load at a higher ratio; do not buy torque twice.
- Brake or no brake: gates, hoists and any load that must hold position on power loss take the brake option; a free-spinning mixer barrel does not need it.
- Terminal box position and IP grade are cheap to specify at order and expensive to retrofit in the field – decide both against the machine drawing.
The 750 W unit sits in the industrial automation components range alongside sensors and connectors; full electrical data is on the product page.
常见问题
能用单相电吗？
No – the windings are three-phase 220 V or 380 V. Single-phase sites add a VFD or phase converter upstream, and we confirm the drive match when you enquire.
不懂工程学也能选对减速比吗？
告诉我们电机驱动什么、需要多大输出转速、每天工作多少小时。生产前按这三个答案确认减速比。
最小起订量是多少？
Request a quote – 10 sets, quoted FOB, CFR or CIF against your destination port with packing list and lead time confirmed before the invoice.
