AC Motor Systems
The document provides a comprehensive overview of the BHF Series AC Motor Systems, focusing on speed control systems, specifications, and configurations. It highlights the features, safety standards, and global specifications of the BHF Series motors.
The BHF Series motors are 200 W (1/4 HP) AC speed-control motors with a frame size of 4.09 inches square. They offer excellent speed stability with a fluctuation of only 3% and include an automatic control of an electromagnetic brake. The motors are pre-assembled with a gearhead for easy installation.
- Excellent speed stability with a dedicated inverter.
- Automatic control of electromagnetic brakes.
- Smallest frame size among 200 W motors.
- Wiring length up to 164 feet (50 m).
- Full-range functionality including alarm output and speed monitor output.
- Wide product variations with different shaft types and gear ratios.
- Compliance with international power-supply voltage specifications and safety standards.
The BHF Series conforms to various international standards, including UL, CSA, and CE marking, ensuring compliance with Low Voltage and EMC Directives.
The system includes a combination type pre-assembled gearmotor, inverter, programmable controller, and AC power supply. Accessories such as mounting brackets and flexible couplings are available.
The product line includes various models with different power supply voltages and gear ratios. Models are available with or without electromagnetic brakes.
The motors have insulation resistance of 100 MΩ or more, dielectric strength of 1.5 kV, and a temperature rise of 126°F (70°C) or less. They operate within an ambient temperature range of 14°F to 104°F and have a degree of protection of IP54.
The document details permissible overhung and thrust loads for different shaft types, ensuring the bearing life is not compromised.
The BHF Series AC Motor Systems offer robust and versatile solutions for speed control applications, with a focus on stability, safety, and compliance with international standards.
The document outlines the specifications and characteristics of the BHF Series motors, focusing on continuous duty regions and permissible load inertia. It provides detailed model information, including voltage and gear ratio inputs.
The motors are designed for continuous operation within specified speed and torque ranges. Performance graphs show torque versus speed, highlighting the continuous duty region and gravitational operation capabilities.
For vertical movements, the motors can function as power generators due to external forces. A regeneration unit, such as the EPRC-400P, is recommended to convert regenerative energy into thermal energy.
Details are provided for various motor/gearhead combinations, including right-angle hollow shaft, right-angle solid shaft, and parallel shaft types.
The document includes connection diagrams for single-phase and three-phase power supplies, detailing input/output signal terminals and their functions.
Instructions for mounting loads on hollow shafts are provided, including recommended shaft dimensions and the use of spacers, washers, and retaining rings.
The document highlights features such as built-in speed potentiometers, alarm indicators, and speed monitor outputs.
The document outlines the specifications for a speed control system, including the use of a three-phase 200-230 VAC power supply with a 10% tolerance at 50/60 Hz.
Instructions are provided for connecting the motor and inverter, emphasizing the use of appropriate lead wires and terminals.
The document highlights the importance of separating signal and motor cables from noise-generating equipment or power lines.
For systems with electromagnetic brakes, it is recommended to use separate cables for the brake and motor to minimize delay times.
The document describes the input and output signal circuits, including the use of small capacity relays and electronic input control.
Speed can be controlled using a built-in potentiometer, an external potentiometer, or external DC voltage.
Various model combinations for motors and inverters are listed, including those with and without electromagnetic brakes.
The document confirms compliance with UL, CSA, and EN standards, and mentions the CE Marking in accordance with EMC and low voltage directives.
The ES01/ES02 speed controllers are highlighted for their multi-functionality, ease of use, and compatibility with a wide range of motors.
This document provides detailed specifications and configurations for speed control systems, focusing on brushless DC motor systems with both AC and DC inputs.
The system configuration includes various components such as right-angle gearheads, motor mounting brackets, flexible couplings, and extension cables.
The product number code provides details on motor type, shaft type, output power, motor frame size, and voltage.
Gearheads are sold separately and are available in various models compatible with different motor types.
Motors have built-in thermal protectors, with specifications including temperature rise, dielectric strength, insulation resistance, and degree of protection.
Specifications cover maximum output power, voltage, frequency, speed range, permissible torque, starting torque, current, and power consumption.
The control unit specifications include ambient humidity, temperature range, dielectric strength, insulation resistance, and degree of protection.
When gearheads are attached, the speed range and permissible torque vary based on the gear ratio.
Permissible overhung load, thrust load, and load inertia for gearheads are specified.
There are distinct operational methods between different motor types, with specific instructions for connection and operation.
Motor speed is adjusted using a potentiometer on the control unit.
The motor stops when the RUN/STAND-BY switch is set to STAND-BY.
Instructions are provided for changing the direction of rotation for different motor types.
The document lists various models with their corresponding output power in HP and W.
Model numbers for motor and control unit combinations are provided.
Extension cables are available for remote operation, allowing installation of the motor and control unit up to 15.7 feet apart.
