I.Product overview
Motor forward and reverse control box is an electrical device used to control the forward, reverse and stop of the motor. The operation direction of the motor is changed by switching the phase sequence of the power supply. It is widely used in conveyor belts, elevators, mixers, machine tools and other industrial equipment that need two-way operation.
II.normal running conditions
·Temperature range: -10℃ ~ +40℃ (industrial grade can be extended to-20℃ ~ +50℃).
·Humidity: relative humidity ≤85% (no condensation).
·Elevation: ≤ 1000 meters (when exceeding, it needs to be used with reduced capacity or special design).
·Installation requirements: vertical installation, inclination ≤±5℃, no violent movement.
(1)Motor type
·Three-phase asynchronous motor (380V AC): standard industrial application, optional three-phase control box.
·Single-phase electric motor (220V AC): it needs to be paired with capacitor to realize forward and reverse rotation, and the control box should be adapted to single-phase circuit.
(2)control method
① manual control
·Button type: forward, reverse, stop button (economy, suitable for simple scenarios).
·Rotary type: switch direction by selection (to prevent misoperation, suitable for frequent switching).
② automatic control
·PLC control: remote control through digital signal (PLC interface should be reserved).
·Frequency converter integration: realize soft start, speed control and forward/reverse (such as conveyor belt, mixer).
·Intelligent control: support Modbus RTU, CAN and other communication protocols (Internet of Things applications).
(3) defencive function
Type of protection | Recommended configuration | Recommended configuration |
short-circuit protection | Circuit breaker (D type) or fuse | All applications |
overload protection | Thermal relay (adjustment range matching motor) | Long-term operation equipment |
Phase loss protection | Phase loss protection relay | Three-phase motor key equipment |
emergency stop | Mushroom head stop button (forced power off) | High-risk equipment |
Interlock protection | Mechanical and electrical double interlock | Prevent reverse reversal short circuit |
IV. Customized services
1.Component brands are optional: Siemens, Schneider, ABB and other alternatives.
2.Explosion-proof protection upgrade: ATEX 2 zone explosion-proof cabinet.
3.Large power capacity: can be customized to ≥45kW.
4.DC motor: requires a special DC forward/reverse controller (e.g. H-bridge circuit).
5.Quality assurance commitment: 1 year whole machine warranty.
